Krsna is like the "Sun-disc" and all of his different expansions of living entities are like the "sun-rays".

Krsna is like the "Sun-disc" and all of his different expansions of living entities are like the "sun-rays".

Krishna the Supreme Personality of Godhead and cause of all causes is like the "Sun Globe" and all of his different expansions are like the "Sunrays" (sakti)

So what are the different categories of Krishna's "parts and parcels" or different expansions?

Krishna's love is based on personal intimate exchanges and reciprocation with His devotees (individual parts and parcels called sakti energy) 

The love Krishna has for His devotees is far greater than any of them can ever have for Him.

Krishna therefore is like the "Sunglobe" and all of His different categories of "sakti" expansions are like the "sunrays".

These "sun-rays" who are the individual living entities, are called the sakti-tattva energy of Krishna however, there are different categories of sakti energy. 

The Sakti-tattva energy of Krishna also includes 4 different individual categories of living entities called 

1 - jiva-tattva, 

2 - shiva-tattva,

3 - Vishnu-sakti-tattva, 

4 - Vishnu tattva.

However the Vishnu-tattva and Vishnu-sakti-tattva expansions are "all-one" with Krishna, unlike the individual jiva-tattva souls who have their own sense of self, personality, character, independence and individuality.

In simple terms, the jiva-tattvas are NOT Krishna, Vishnu-tattva or Vishnu-sakti-tattva.

Shiva-tattva is in a league of his own, he is neither jiva-tattva, Vishnu-sakti-tattva or Vishnu-tattva.

In this way Sakti-tattva is divided into four categories, all are like the Sunrays and Krishna is like the central Sun globe surrounded by the Sunrays.

These sunrays (sakti) perpetually  emanating from and surrounding the Sun (Krishna) are in different categories.

So what are the categories of Krishna's sakti ("parts and parcels") that are all different expansions of Krishna?

1 - Vishnu-tattvas have 93.75% of Krishna's qualities which is 60 attributes out of Krishna's 64 attributes, like Krishna's older brother Balarama, and Vishnu or Narayana in each Vaikuntha Planet, or Maha Vishnu, Garbhodakashayi Visnu and Paramatma who enter the material creation.

2 - Sakti-vishnu-tattvas have 93.75% of Krishna's qualities which is 60 attributes out of Krishna's 64 attributes, like Srimati Radharani, some leading gopis and gopas and other associates and residents of Vrindavan, including many others who appear in Lord Caitanya Mahaprabhu's lila or pastimes on Earth.

None of these can ever fall down to the material world because they ARE "direct" expansions of Krishna, meaning they ARE Krishna's personality expressed in a different way according to pastime. 

In other words both Vishnu-tattva and Vishnu-sakti-tattvas ARE Krishna Himself playing another role in His own pastimes.

Many of the living entites are both Vishnu-sakti-tattvas and Vishnu-tattvas in the Spiritual World of Goloka-Vrindavana and the unlimited Vaikuntha planets, and many others are also jiva-tattva souls like us. 

And, as explained above, both Vishnu-tattva and Vishnu-sakti-tattva can NEVER fall down and forget Krishna because THEY are already the full expansions of Krishna's personality just playing another role in His unlimited pastimes (lilas) in either the Vaikuntha Planets, Goloka Vrindavan, or in the material creation.

In other words, all Vishnu-tattva and Vishnu-sakti-tattva ARE Krishna in a different forms experiencing His own pastimes.

3 - Shiva-tattva has 84.375% of Krishna's qualities which is 54 attributes out of Krishna's 64 attributes.

Lord Shiva is in a league of His own. 

Many scholars believe Hanuman is an incarnation of Shiva, but not all. There are many incarnations of Shiva however, he can never be Vishnu-tattva or Vishnu-sakti-tattva. 

Although Shiva and a Vishnu-tattva form can merge as one which really means a Vishnu-tattva form is in "the mood" of Shiva. 

Once Lord Caitanya Mahaprabhu adapted the "mood" of Shiva, not that He is Shiva. 

This can also be the same for other Vishnu-tattva expansions that are tinged with Lord Shiva's attributes. 

4 - Jiva-tattvas have 78.125% of Krishna's qualities which is 50 attributes out of Krishna's 64 attributes.

The Jiva-tattvas are known as the "marginal living entities", they are also Krishna's sakti expansions but NOT direct full expansions like Vishnu-tattva and Vishnu-sakti-tattva explansions or a special expansion in a league of their own like Shiva-tattva. 

The individual jiva-tattvas or marginal living entities are NOT directly krishna like the above 2 categories of Vishnu-tattva and Vishnu-sakti-tattva are.

Shiva is NOT Vishnu-tattva, Vishnu-sakti-tattva or jiva tattva). 

The jiva-tattvas or marginal living entities are independent free thinking thinking living entities who have full free will in the Spiritual Planets (not fully in the material creation though). 

The jiva souls in their full potential in both Vaikuntha and Goloka-Vrindavana, are individual living entities with their own sense of self, personality, individuality and character eternally who can choose for themselves how to serve Krishna, or even not serve Him if they choose.

The marginal living entities (jiva-tattvas) are also known as the jiva soul or jivatma, they have their own "sense of individual self" that is independent and separate from Krishna's personality, therefore, they are their own person yet are always fully dependent on Krishna's energies whether in the Spiritual or material worlds. 

This is because EVERYTHING is under His control because Krishna is the Supreme Personality of Godhead and cause of all causes.

In this way, all jiva-tattva souls have free will eternally as part of their marginal spiritual make up that allows them to have the ability to choose for themselves in both Vaikuntha and Goloka Vrindavan as part of their marginal constitution.

This means, as separate thinking living entities, the jiva soul can choose to be with Krishna or Vishnu, or reject the Lord and enter the material creation if they want, such freedom ONLY fully exists in Vaikuntha and Goloka Vrindavana.

In the material creation freedom is almost none existant because as soon as the jiva-tattva soul takes a material bodily vessel, the embodied soul becomes trapped and entangled under the influence of material nature.

The hash control from material nature includes the animalistic instincts of eating, sleeping, mating and defending that directs and forces the destiny of all lower species of life.

No karma is created in the lower species of life in the material creation or the heavenly and hellish planetary systems.

There are only the reactions to one's deeds "pious or impious", while in the rare human bodily form on this Earth Burloka, can create karma.

In the human form, the embodied jiva soul must take responsibility for their actions.

Also because material time is divided into past, present and future, each material bodily container experiences birth, youth, disease, middle age, old age and death.

Material time means one's existence is in a constant progression of decline and decomposition, nothing lasts in the material creation, everything eventually fades away in oblivion.

Eventually in the material creation, the trapped jiva soul becomes frustrated with the temporary nature of material life, and the constant changing of material bodies due to them always being in a state decline and decomposition, causing them to eventually wear out due to this decay, then eventually cease to function.

This leads to rebirth or the cycle of birth and death.

The trapped jiva soul therefore can choose to escape the material creation and enter the impersonal Brahmajyoti effulgence and hover inactively their in a dormant state for billions of years if they want.

However, merging into the impersonal Brahmajyoti or Brahman as an individual inactive impersonal formless spark, is artificial and only temporary.

Even if one foolishly believes it's for eternity or one's original position, then they are being decieved. No, the impersonal Brahmajyoti is NOT the jiva souls's original position or source.

The impersonal Brahmajyoti or Brahman is a fallen condition the jiva souls eventually falls too from their originally position in Vaikuntha or Goloka Vrindavan, no jiva soul originates from this nonsense inactive "clear sheet of consciousness" within the impersonal brahman or Brahmajyoti.

They first fall to the material creation and take birth, then after millions of years of being frustrated with the temporary nature of material existence, they can fall further thinking it is liberation by merging into the impersonal Brahmajyoti (Brahman effulgence)

Eventually ALL jiva souls fall out of the impersonal Brahmajyoti or Brahman effulgence too because it is NOT permanent, nor is it one's original position or home as already explained. 

The fallen jiva soul then again takes birth in lower species of material life.

From there, they have to progress within 8 million 4 hundred thousand  species of life, moving through the cycle of birth and death for millions of bodies, taking millions of years, until they again get back to the human species of life.

Only in the human material bodily vessel can the jiva soul again have the opportunity to realize "their full potential" as a spiritual individual person and form (vigraha) originally from Vaikuntha by living under the guidance and direction of a bonafide Spiritual Master like Srila Prabhupada, who can take the fallen jiva soul back home, back to Godhead.

Fortunately for most jiva souls or marginal living entities, over 90%, according to Srila Prabhupada, NEVER make this foolish troublesome choice and enter the mundane decaying material creation of constant suffering and experiencing repeates birth and death.

The following is from the Book "Teachings of Lord Caitanya"-

Srila Prabhupada - "There are forms of Kṛṣṇa that are a little different from His original form, and these are called tad-ekātma-rūpa forms. 

These may be further divided into the vilāsa and svāṁśa forms, which in turn have many different features and can be divided into prābhava and vaibhava forms.

As far as the vilāsa forms are concerned, there are innumerable prābhava-vilāsas, headed by Kṛṣṇa's expansions as-

Vāsudeva, 

Saṅkarṣaṇa, 

Pradyumna,

Aniruddha. 

Sometimes the Lord thinks of Himself as a cowherd boy, and sometimes He thinks of Himself as Vasudeva's son, a kṣatriya prince, and this "thinking" of Kṛṣṇa is called His "pastimes." 

Actually, Krishna is in the same form in His vaibhava-prakāśa and prābhava-vilāsa, but He appears differently as Kṛṣṇa and Balarāma" (Teachings of Lord Caitanya)

Percentages of Krishna's 64 qualities that others have mathematically work out as follows -

Vishnu-tattva and Vishnu-sakti-tattva Forms of the Lord have 60 qualities.

So how much is 60 qualities out of 64 qualities written as a percentage exactly?

Convert fraction (ratio) 60/64

Answer: 93.75%

Shiva-tattva - How much is 54 out of 64 written as a percentage?

Convert fraction (ratio) 54/64

Answer: 84.375%

Jiva-tattva - How much is 50 out of 64 written as a percentage?

Convert fraction (ratio) 50/64

Answer: 78.125%

Lord Krishna is the Supreme Personality of Godhead and cause of all causes.

Krishna is the ORIGINAL Form of God from whom ALL His Vishnu and Narayana forms expand from.

This means the only difference between Srimati Radharani and Krishna, and Lord Balarama and Krishna, is Lord Krishna IS the Supreme Personality of Godhead and ORIGINAL cause of all causes, and has an extra 4 qualities MORE than both Radharani and Balarama (His Vishnu-tattva and Vishnu-sakti-tattva expansions).

Therefore, not even Srimati Radharani or Balarama (Krishna's older brother) have 64 unique qualities like Krishna, they also have only 60 qualities which is 93.75% of Krishna's 64 qualities that is 100%.

Lets make this easy to understanding -

Lord Krishna has 64 qualities which is "exactly" 100% of those unique set qualities.

Vishnu-tattva and Vishnu-sakti-tattva have 60 qualities or "exactly" 93.75%.

Shiva-tattva has 54 qualities or "exactly" 84.375%.

Jiva-tattva has 50 qualities or "exactly" 78.125%..**..
