The "Sun-disc" and the "sun-rays" both only exist when together but there is a difference between the two, the molecules of the sun-rays are not equal to the molecules of the Sun-disc, similarly the jiva-souls are not equal with Krsna.

Here, Krsna is compared to the Sun-disc and the marginal living entities (jiva-souls) are compared to the surrounding sun-rays or sunshine.

Just like the "sun-rays" are not equal to the "Sun-disc", similarly, not even the various varieties of Krsna's direct Visnu-tattva expansions also are NOT equal to Krsna, except for Krsna's eternal consort Srimati Radharani.

By this example we can also understand that the Sun-disc and the sun-rays can NEVER be separated or exist without each other. 

In other words, Krsna the Supreme Personality of Godhead and cause of ALL causes, is ALWAYS surrounded by His parts and parcels (the various kinds of living entities that are in two categories, Viṣṇu-tattva and jiva-tattva [jiva-souls]) and can NEVER be separated from them.

Srila Prabhupada – "In the Padma Purana, wherein it is said that there are two kinds of spiritual entities; one is called the jiva-tattva, and the other is called the Visnu-tattva." (87th Chapter Krsna Book, Prayers by the Personified Vedas)

Srila Prabhupada - "The jiva-souls are simultaneously one with Krsna and Rādhā yet at the same time different." (lecture in Montreal, June 10, 1968)

All living entities ARE expansions of the Supreme Personality of Godhead Krsna, who has simultaneously expanded Himself as His various individual parts and parcels.

As said above, the various types of living entities number in two categories, Visnu-tattva and jiva-tattva or jiva-souls.

From the Sun-disc, the sun-rays are maintained and exist simultaneously as an extension of the Sun-disc, similarly this also means Krsna and the living entities can NEVER exist without each other. 

This further means Krsna is fully complete AS Himself, who can NEVER be alone because Krsna is EVERYTHING and EVERYTHING resides in Him.

Krsna is ALWAYS enjoying with His unlimited expansions who are eternally His parts and parcels, just like the Sun-disc is always surrounded by the sun-rays,  similarly Krsna is always surrounded by His parts and parcels.  

And just like it is impossible for the Sun-disc to exist without the sun-rays, similarly it is impossible for Kṛṣṇa to exist without His loving devotees headed by Srimati Radharani.

Therefore, just like the Sun-disc has no meaning without the sun-rays, similarly Krsna has no meaning without His devotees (parts and parcels) therefore it is impossible to separate Kṛṣṇa from His parts and parcels.

The possibility of Krsna being without His devotees (expansions) can NEVER exist because there was never a time Krsna and the living entities did not exist together Bhagavad Gita teaches, Chapter 2 Text 12.

Bhagavad Gita - "Never was there a time when I did not exist, nor you, nor all these kings; nor in the future shall any of us cease to be." (BG 2.12)

The jiva-souls and Kṛṣṇa have always existed and were NEVER created.

Srila Prabhupada – "There are no new souls, new and old are due to this material body, but the jiva-soul is never born and never dies, so if there is no birth, how can there be new souls?" (Letter to Jagadisa dasa, 7/9/1970)

The reason why Krsna is fully complete within Himself is understood in this way-

Krsna is NEVER alone as one, and has never been alone as one,p1¹ Krsna is always in the company of two because loving exchanges and reciprocation can only exists in a relationship between two.

This means Krsna is "simultaneously" one individual Personality, and at the same time "many Personalities" but inconceivable different from all of them.

Krsna therefore is simultaneously one and different from all there is.

This means He can NEVER be alone because He is already EVERYTHING and EVERYTHING is always part and parcel of Him.

Kṛṣṇa's closest associate is His eternal consort Srimati Rādhārāṇī who represents His internal potency. Radharani eternally intensifies the pleasure of Śrī Kṛṣṇa, so how can Kṛṣṇa ever be alone? 

All the devotees of Krsna must win the attention of Srimati Radharani to get Krsna's attention, as all service to Krsna only reaches Him by going through Her.

Srila Prabhupada - "I offer my respects to Rādhārāṇī, whose bodily complexion is like molten gold and who is the Queen of Vṛndāvana. You are the daughter of King Vṛṣabhānu very dear to Lord Kṛṣṇa. 

So if we approach Kṛṣṇa through Rādhārāṇī, through the mercy of Rādhārāṇī, then it becomes very easy. If Rādhārāṇī recommends that "This devotee is very nice," then Kṛṣṇa immediately accepts, however fool I may be. 

Because it is recommended by Rādhārāṇī, Kṛṣṇa accepts. Therefore, in Vṛndāvana you'll find all the devotees, they're chanting more Rādhārāṇī's name than Kṛṣṇa's. Wherever you'll go, you'll find the devotees are addressing, "Jaya Rādhe." You'll find still in Vṛndāvana. They are glorifying Rādhārāṇī. They're more interested, worshiping Rādhārāṇī. 

Because however fallen I may be, if some way or other I can please Rādhārāṇī, then it is very easy for me to understand Kṛṣṇa. However, if you go by the speculative process to understand Kṛṣṇa, it will take many, many lives. But if you take devotional service, by just trying to please Rādhārāṇī, then Kṛṣṇa will be won over very easily. 

Because Rādhārāṇī can deliver Kṛṣṇa. She is such a great devotee, the emblem of mahā-bhāgavata. Even Kṛṣṇa cannot understand what is Rādhārāṇī's quality. Even Kṛṣṇa, although He says vedāhaṁ samatītāni (BG 7.26), "I know everything," still, He fails to understand Rādhārāṇī. Rādhārāṇī is so great.

Actually, Kṛṣṇa knows everything but in order to understand Rādhārāṇī, Kṛṣṇa accepted the position of Rādhārāṇī. Kṛṣṇa wanted to understand the potency of Rādhārāṇī. Kṛṣṇa thought that "I am full. I am complete in every respect, but still, I want to understand Rādhārāṇī". 

Why is this so?

This propensity made Kṛṣṇa obliged to accept the propensities of Rādhārāṇī, to understand Kṛṣṇa, Himself. These are, of course, very transcendental, great science. One who is advanced in Kṛṣṇa consciousness and well conversant with the śāstras, they can understand. But still, we can discuss from the śāstra. 

When Kṛṣṇa wanted to understand Himself, He took the tendency of Śrīmatī Rādhārāṇī. And that is Caitanya Mahāprabhu. Rādhā-bhāva-dyuti-suvalitam. Caitanya Mahāprabhu is Kṛṣṇa, but He has accepted the propensities of Rādhārāṇī. As Rādhārāṇī is always in feelings of separation of Kṛṣṇa, similarly, in the position of Rādhārāṇī, Lord Caitanya was feeling separation of Kṛṣṇa. 

This is the teachings of Lord Caitanya, feelings of separation, not meeting. The process of devotional service taught by Caitanya Mahāprabhu and His disciplic succession is how to feel separation from Kṛṣṇa. This is Rādhārāṇī's position, ALWAYS feeling the separation."(Radhastami, Srimati Radharani's Appearance Day, London, Aug 29, 1971)

Srila Prabhupada - "Regarding your question about our relationship with Srimati Radharani, She is the internal energy, we are marginal energy. Marginal means sometimes internal, sometimes external. 

When we are under the internal energy, that is our normal life, and when we are under the external energy, that is our abnormal life. 

Therefore, we are called marginal energy; we can be either this way or that way. But being qualitatively one with the purusa, our tendency is to remain in the internal energy. Being in the external energy is our artificial attempt." (Letter to Lilavati, Allston, Mass 25 April, 1969)

Does the original Kṛṣṇa in Vṛndāvana ever leave Vṛndāvana?

Srila Prabhupada - "When Kṛṣṇa kills the demons outside Vṛndāvana, He is not original Kṛṣṇa; He is Vāsudeva (Visnu-tattva). Vāsudevaḥ sarvam iti (BG 7.19). When Kṛṣṇa is acting universally, that is Vāsudeva (Visnu-tattva). The original Kṛṣṇa is ALWAYS in Vṛndāvana."

Jayatīrtha - "If the original Kṛṣṇa is always in Vṛndāvana, then why do the gopīs and Rādhārāṇī feel separation from Him?"

Srila Prabhupada - "That is here, in this material world. In the spiritual world Kṛṣṇa does not leave."

Jayatīrtha - "Oh."

Srila Prabhupāda - "And even in the material world, Kṛṣṇa superficially has gone to Mathurā, but He has captured the heart of the gopīs. So He is not leaving. Gopīs are enjoying Kṛṣṇa by separation. That is Caitanya Mahāprabhu's feeling, how He is appreciating Kṛṣṇa by separation." (Morning Walk, July 17, 1975, San Francisco)

Guest - "What category is Radharani in?"

Srila Prabhupada - "She is śakti, Cit-śakti. Bhagavān ke pleasure potency. Śakti, śakti-tattva, Śaktimān. Bhagavān is Śaktimān, and that śakti is Rādhārāṇī or Sītā or Lakṣmī. Durgā is also śakti, another feature of Rādhārāṇī."

Guest - "Śakti in original form is Rādhā?"

Srila Prabhupāda - "Yes, Parāsya śaktih..., parāsya śaktir vividhaiva śrūyate (CC Madhya 13.65, purport). Originally cit-śakti. That cit-śakti is expanding. Just like we are..., rāmādi mūrtiṣu kalā-niyamena tiṣṭhan (Bs. 5.39). Kalā means part and parcel. So we are also part and parcel, but we are very small part and parcel. But rāmādi mūrti, they are bigger part and parcel. Just like if you throw one brick on the floor, so there will be so many small particles, big particles, this particle, that. 

They are all part and parcel of the brick, but one part very small atomic part, and one big part, this part, this part, then this part, then this part. 

So all, Kṛṣṇa is the origin, and everyone is part and parcel. Some of them are bigger and some of them are smaller. So Viṣṇu-tattva is almost like Kṛṣṇa."

Guest - "Like Kṛṣṇa?"

Srila Prabhupāda - "Others, they are very small. So according to the size, or according to the power."

Guest - "Power?"

Srila Prabhupāda - "The part and parcel exercises his position. Some of them are Viṣṇu-tattva, some of them are Jīva-tattva, some of them are Śakti-tattva and some of them para-tattva. Like that."

Guest - "Para-tattva?"

Srila Prabhupāda - "Para-tattva is Bhagavān. Para-tattva means Kṛṣṇa, Rāma, Nārāyaṇa, Viṣṇu. These are all para-tattva. Bhagavān avatāra, rāmā, nṛsiṁha, varāha, kūrma, vāmana, daśāvatāra, all avatāra. Or śakti-tattva, material energy, aparā-tattva, matter. 

Similarly cit-tattva is spiritual world. The living entities, although they are in the material world, they belong to the spiritual world. Therefore Kṛṣṇa says, apareyam. This material energy is inferior. Itas viddhi me prakṛtiṁ parām. Beyond this material world is another, superior energy that includes jīva-bhūta and jiva-tattva." (Room Conversation, Nov 11, 1971, New Delhi)

This is the fullness of Lord Krsna.

This is why Krsna is the Supreme Personality of Godhead and cause of ALL causes because He is EVERYTHING and EVERYTHING is in Him.

Krsna is fully satisfied in Himself, that includes enjoying through all of His expansions that are His parts and parcels. Krsna is ALWAYS with His marginal living entities (jiva-souls).

The fact is all Visnu-tattva and jiva-tattva expansions are part and parcel of Krsna, just like the sun-rays and part and parcel of the Sun-disc.

In other words, Krsna is NEVER alone just like the Sun-disc can never be alone due to the presence of the surrounding sun-rays. 

Krsna is compared to the Sun-disc and the different types of living entities are compared to the sun-rays.

The Sun-disc and the sun-rays cannot exist without each other, similarly Krsna is always surrounded by His parts and parcels and has no meaning without them.

In this way, Krsna IS the Supreme Lord and simultaneously one with all that there is, BUT also different and independent from all of His expansions too.

However, Krsna CANNOT exist separately "alone" without His devotees headed by Srimati Radharani.

Krsna and Radharani can NEVER be divided or separated.

Krsna's eternal consort Srimati Rādhārāṇī is the manifestation of Krsna's pleasure potency.

Guest - "Srila Prabhupāda, are we expansions of Rādhā?"

Srila Prabhupada - "No, Rādhā is the internal potency, we are marginal potency. Of course, originally, in that sense, everything is Kṛṣṇa's expansion. Sarvaṁ khalv idaṁ brahma. But even there are expansions... That is the difference between Māyāvāda philosophy and Vaiṣṇava philosophy. 

Caitanya Mahāprabhu teaches acintya bhedābheda. We are always simultaneously one and different. Always. We should remember. We are expansion of Kṛṣṇa, we are expansion of Rādhā also because Rādhā is also expansion of Kṛṣṇa. But still, different. That is our philosophy- 

"One and different simultaneously - Acintya bhedābheda."

Caitanya Mahāprabhu's philosophy is inconceivable simultaneously one and different. This is explained in the Seventh Chapter of Bhagavad-gītā. The energies and the energetic is the same. Śakti-śaktimator abheda.

Just like sun and the sunshine, they are the same. There is no difference. But the molecules of the sunshine particles, that is not equal to the sun. These truths we shall always remember. Acintyāḥ khalu ye bhāvāḥ. Therefore these are inconceivable. We are simultaneously one with Kṛṣṇa and Rādhā, and at the same time different." (Lecture on BG 4.5 - Montreal, June 10, 1968)

Srila Prabhupada - "Rādhā and Kṛṣṇa are "one and the same", but They have assumed two bodies. Thus They enjoy each other, tasting the mellows of love. The two transcendentalists Rādhā and Kṛṣṇa are a puzzle to materialists. The description of Rādhā and Kṛṣṇa from the diary of Śrīla Svarūpa Dāmodara Gosvāmī is a condensed explanation, but one needs great spiritual insight to understand the mystery of these two personalities.

One is enjoying in two.

Śrī Kṛṣṇa is the potent factor, and Śrīmatī Rādhārāṇī is the internal potency. According to Vedānta philosophy, there is no difference between the potent and the potency; they are identical. We cannot differentiate between one and the other, any more than we can separate fire from heat.

Everything in the Absolute is inconceivable in relative existence. Therefore in relative cognizance it is very difficult to assimilate this truth of the oneness between the potent and the potency. The philosophy of inconceivable oneness and difference propounded by Lord Caitanya is the only source of understanding for such intricacies of transcendence.

In fact, Rādhārāṇī is the internal potency of Śrī Kṛṣṇa, and She eternally intensifies the pleasure of Śrī Kṛṣṇa. 

Impersonalists cannot understand this without the help of a mahā-bhāgavata devotee. 

The very name “Rādhā” suggests that Śrīmatī Rādhārāṇī is eternally the topmost mistress of the comforts of Śrī Kṛṣṇa. As such, She is the medium transmitting the living entities’ service to Śrī Kṛṣṇa. Devotees in Vṛndāvana therefore seek the mercy of Śrīmatī Rādhārāṇī in order to be recognized as loving servitors of Śrī Kṛṣṇa." (CC, Adi 4.56, Translation and Purport)

All the devotees of Krsna must win the attention of Radharani to get Krsna's attention, as all service to Krsna only reaches Krsna by going through Her.

Srila Prabhupada - "When Krsna wants to be attracted by a woman, He has to create such a woman from His own energy. That woman is Rādhārāṇī." (SB Canto 3 Ch 31 text 38 Purport)

Krsna divided Himself into "two" so He could experience loving exchanges. 

For even Krsna, love can NEVER exist when there is just "one", there MUST be two, His expansions like Srimati Radharani and His Visnu-tattva and jiva-tattva expansions.

To experience the ultimate loving exchanges and emotions with a women, Krsna divided Himself into two. 

Therefore Srimati Radharani and Krsna are one.

Krsna wanted to experience loving emotions and affection, this is why He divided Himself into two separate bodily Forms - Radha and Krsna, just so He could experience equal loving exchanges.

So how to understand Srimati Radharani?

Madhudviṣa Swami - "Śrīla Prabhupāda, you spoke of inferior energy and superior energy. Those are two general categories. Are there other categories of energies besides that, and specifically how could we understand Śrīmatī Rādhārāṇī Is She?"

Srila Prabhupāda - "She is spiritual energy."

Madhudviṣa Swami - "But is She jīva-bhūta or?"

Srila Prabhupada - "No, She is Kṛṣṇa. If everything is Kṛṣṇa and Rādhārāṇī is not Kṛṣṇa, what is that? Kṛṣṇa. He (She) is Kṛṣṇa. She is the Kṛṣṇa's pleasure potency."

Madhudviṣa Swami - "She is not jīva-soul?"

Srila Prabhupada - "No, no, no. She is Kṛṣṇa. Kṛṣṇa divided Himself into His energy and Himself. That energy, original spiritual energy, is Rādhārāṇī. That is stated by Jīva Gosvāmī. Rādhā kṛṣṇa-praṇaya-vikṛtir hlādinī śaktir asmāt. When Kṛṣṇa wants pleasure, He cannot accept the inferior energy. 

The same superior energy, Kṛṣṇa, is divided into two. That is Rādhā and Kṛṣṇa. And again, when they unite, that is Caitanya Mahāprabhu. 

Divided, they are Rādhā and Kṛṣṇa, and united, Caitanya Mahāprabhu. 

Śrī-kṛṣṇa-caitanya rādhā-kṛṣṇa nahe anya. Anya means another. 

So Śrī Kṛṣṇa Caitanya is combination of Rādhā and Kṛṣṇa. And when they are divided into two, that is Rādhā and Kṛṣṇa. 

This is the purport. Rādhā kṛṣṇa-praṇaya-vikṛtir hlādinī śaktir asmād ekātmānāv api bhuvi purā deha-bhedaṁ gatau tau, śrī-caitanyākhyaṁ prakaṭam adhunā tad-dvayaṁ caikyam āptam [Cc. Ādi 1.5]. 

These are the conclusion. Śrī Caitanya Mahāprabhu is Rādhā-Kṛṣṇa combination. But He is playing the part of Rādhārāṇī to understand Kṛṣṇa. 

This is Caitanya Mahāprabhu. 

Rādhārāṇī is the chief gopī and all Her young girl friends, they are also gopīs." (Lecture on SB, Canto 1 Ch 1-5 - Melb, Australia June 26, 1974)

Caitanya Caritamrita - "Rādhikā is the transformation of Kṛṣṇa’s love. She is His internal energy called hlādinī." (CC, Adi 4.59 Translation)

Srila Prabhupada - "Radharani's mind, senses and body are steeped in love for Kṛṣṇa. She is Kṛṣṇa’s own energy, and She helps Him in His pastimes. 

Śrīmatī Rādhārāṇī is as fully spiritual as Kṛṣṇa. No one should consider Her to be material. She is definitely not like the conditioned souls, who have material bodies, gross and subtle, covered by material senses. She is all-spiritual, and both Her body and Her mind are of the same spiritual embodiment. 

Because Her body is spiritual, Her senses are also spiritual. Thus Her body, mind and senses fully shine in love of Kṛṣṇa. She is the personified hlādinī-śakti (the pleasure-giving energy of the Lord’s internal potency), and therefore She is the only source of enjoyment for Śrī Kṛṣṇa. Śrī Kṛṣṇa cannot enjoy anything that is internally different from Him. 

Therefore Srimati Rādhārani and Śrī Kṛṣṇa are identical. 

The sandhinī portion of Śrī Kṛṣṇa’s internal potency has manifested the all-attractive form of Śrī Kṛṣṇa, and the same internal potency, in the hlādinī feature, has presented Śrīmatī Rādhārāṇī, who is the attraction for the all-attractive. No one can match Śrīmatī Rādhārāṇī in the transcendental pastimes of Śrī Kṛṣṇa." (CC, Adi 4.71, Translation and Purport)

Caitanya Caritamrita - "Just as the fountainhead, Lord Kṛṣṇa, is the cause of all incarnations, so Śrī Rādhā is the cause of all these consorts." (CC Adi 4.76, Translation)

Caitanya Caritamrita - "Rādhā is the one who gives pleasure to Govinda, and She is also the enchantress of Govinda. She is the be-all and end-all of Govinda, and the crest jewel of all His consorts." (CC, Adi 4.82, Translation)

Caitanya Caritamrita - "The transcendental goddess Śrīmatī Rādhārāṇī is the direct counterpart of Lord Śrī Kṛṣṇa. She is the central figure for all the goddesses of fortune. She possesses all the attractiveness to attract the all-attractive Personality of Godhead. She is the primeval internal potency of the Lord." (CC Adi 4.83, Translation)

Srila Prabhupada - "When Krsna wants to be attracted by a woman, He has to create such a woman from His own energy. 

That woman is Rādhārāṇī. 

It is explained by the Gosvāmīs that Rādhārāṇī is the manifestation of the pleasure potency of the Supreme Personality of Godhead. When the Supreme Lord wants to derive transcendental pleasure, He has to create a woman from His internal potency and that women is Srimati Radharani." (SB Canto 3 Ch 31 text 38, Purport)

Krsna divided Himself into "two" just so He could experience loving exchanges with a women and gave Her the name Srimati Radharani. Love can only exist when there are "two or more" involved in loving reciprocations and exchanges. 

Srila Prabhupada - "We have got the propensity to love. Love means somebody else. Love cannot be "one" or love cannot be executed only one, there must be another one. I love somebody; somebody loves me, there must be lover, there must be beloved, and the transaction, then love." (Lecture on SB, Canto 1 Ch 2 text 6, Delhi, Nov 12, 1973)

Srila Prabhupāda – "Love means two persons, then there is exchange, then there is love. I must deal with you open-hearted, you must deal with me open-hearted, then there is love. So if you want to love Kṛṣṇa, God, then these things must be there." (Aug 9, 1976, Tehran)

However, Krsna is ALWAYS complete in Himself and is NEVER alone because within Krsna energies are EVERYWHERE, and therefore can become two personalities or more anytime likes.

For example, Krsna is always enjoying in Vrindavana with His consort Srimati Radharani, who Krsna created by dividing Himself into two, just so He could experience loving exchanges with a women.

In this way Krsna is "FULLY COMPLETE" as Himself due to enjoying unlimited pastimes with-

1 - With His internal energy headed by Srimati Radharani who is none different than Krsna.

2 - His Visnu-tattva expansions (unlimited Visnu/Narayana expansions including Balarama who is Kṛṣṇa's first expansion and from whom all other Visnu expansions expand from.

Both Visnu-"sakti"-tattvas and Visnu-tattvas have 93.75% of Krsna’s qualities which is having 60 of Krsna's 64 attributes.

The above two categories ARE direct expansions of Krsna where He is playing a different role in His own pastimes.

3 - His Siva-tattva expansions who can be many personalities who are actually expansions of Siva) 

4 - His jiva-tattva (jiva-souls) expansions (marginal living entities (individual jiva-tattva-souls) who are all endowed with free will and a personality separate from Krsna's Personality.

These two (Siva-tattva and jiva-tattva) are NOT God (Krsna or Visnu) meaning they are NOT Visnu-"sakti"-tattva (internal potency) or Visnu-tattva (Visnu/Narayana expansions). 

Siva has 85.938% of Krsna's qualities, having 55 of Krsna's 64 attributes.

The jiva-souls have 78.125% of Krsna's qualities having 50 of Krsns's 64 attributes.

Both Siva and the jiva-souls have independent personalities separate from Krsns's Personality, so they can NEVER be God like Visnu or Krsna.

However, they are ALWAYS dependent on Krsna the Supreme Personality of Godhead and maintainer and cause of ALL causes. 

These living entities manifest as different categories of Krsna's energies but can NEVER be separated from Krsna, just like the sun-rays can NEVER be separated from the Sun-disc.

But His greatest pleasure comes from Srimati Radharani His eternal consort and internal potency.

Krsna is NEVER alone due to EVERYTHING being completely situated within Him. 

Krsna is simultaneously one and different from His energies, as an independent individual Person, and as His different expansions also. 

Krsna is EVERYTHING and EVERYTHING is part and parcel of Krsna.

This is the top most realization of Krsna's full potential as the Supreme Personality of Godhead and cause of ALL causes, who is naturally fully satisfied in Himself because EVERYTHING is Him including Srimati Radharani.

Yet simultaneously different from Him like the Sun-disc and the sun-rays, making Krsna fully complete and NEVER alone.

This obviously means ALL His different expansions such as Visnu-tattva, Visnu-"sakti"-tattva and jiva-tattva (jiva-souls), are His part and parcels.

Krsna IS the Supreme Personal Lord (God) as His own individual bodily (vigraha) Form, yet simultaneously expands as ALL other living entities too, who expand from Him like the sun-rays surround the Sun-disc.

For example-

Srila Prabhupada - "Rādhā and Kṛṣṇa are "one and the same", but They have assumed two bodies. Thus They enjoy each other, tasting the mellows of love. One is enjoying in two, we cannot differentiate between one and the other, any more than we can separate fire from heat.

The philosophy of inconceivable oneness and difference propounded by Lord Caitanya is the only source of understanding for such intricacies of transcendence. 

In fact, Rādhārāṇī is the internal potency of Śrī Kṛṣṇa, and She eternally intensifies the pleasure of Śrī Kṛṣṇa. Impersonalists cannot understand this without the help of a mahā-bhāgavata devotee. 

The very name “Rādhā” suggests that Śrīmatī Rādhārāṇī is eternally the topmost mistress of the comforts of Śrī Kṛṣṇa. As such, She is the medium transmitting the living entities’ service to Śrī Kṛṣṇa. Devotees in Vṛndāvana therefore seek the mercy of Śrīmatī Rādhārāṇī in order to be recognized as loving servitors of Śrī Kṛṣṇa." (CC, Adi 4.56, Translation and Purport)

Srila Prabhupada - "When Krsna wants to be attracted by a woman, He has to create such a woman from His own energy. That woman is Rādhārāṇī." (SB, Canto 3 Ch 31 text 38 Purport)+++
