By Krsna's (God's) grace and will, He has allowed His individual jiva-souls or marginal living entities (His devotees) to have their own unique distinctive personality, character and freedom of expression (free-will).

This allows Krsna's devotees (the individual jiva-souls) to paradoxically appear independent and separate from Krsna's Personality and absolute control. However, the genuine devotees of Krsna know that is never the case, and never possible. 

The pure devotees of Krsna understand that Krsna is the source of all that there is, simply because "everything" there is eternally belongs to Him as an individual Person as a spiritual Form, who is similtaneously an all pervasive energy meaning Krsna is one yet different from His creation.

Also, what happens similtaneously with His individual devotees when they eternally experience their unique distinctive freedom of expression, is Kṛṣṇa always remains the cause of all causes, meaning, as said above, is behind the individual devotee's expression of free will always.

In other words, everything the individual jiva-souls (devotees) choose to do, or choose not to do, must be first sanctioned by Krsna. In this way, not a blade of grass in Krsna's creation can move without the will of Krsna.

The devotee's (the individual jiva-soul's) free will explained above is actually a paradox in Krsna's creation of the spiritual and material worlds, where He already knows everything - their past, present and future, because He alone also allows the individual jiva-souls (His devotees) to eternally have a minuscule expression of the same free will and independence that He eternally has.

Krsna can sanction this, or anything He wants in His creation, after all, He is the Supreme Personality of Godhead and cause of all causes, who can do what ever He wants. 

Kṛṣṇa can causelessly appear before any of us at anytime He chooses, but generally wants His pure devotees to bring us to Him, that is why He sent Srila Prabhupāda all over the world to bring us all back home, back to Godhead.

Krsna therefore has allowed this unique distinctive independent expression His devotees have so they can voluntarily choose to play their part in a "two-sided" devotional relationship with Krsna, based on cooperation, personal contributions and reciprocation. 

Such a "two-sided" loving  relationship between Krsna and His devotees creates diversity, mystery, loving exchanges and unique contributions (offerings) 

This allows the individual jiva-souls (devotees) to choose their own unique contributions they want to offer to Krsna.

Krsna permits this to happen so that offerings coming from His devotee's (the individual jiva-soul's) are always voluntary, that further expand the relationship by creating suprise and mystery within Krsna's eternal Abode.

We must also understand that Krsna (God) is eternally simultaneously one with His creation, and different from it, He is everything and in everything, and is similtaneously an individual Person as an eternal spiritual Bodily Form

Krsna has allowed the individual jiva-souls (devotees) to have their own unique distinctive personality and character separate from Krsna's Personality, Bodily Form and absolute control.

Although Krsna is always the cause of all causes and all that there is, meaning He is behind everything as explained above. 

As also said above, Krsna allows His creation to be this way so the free will His devotees express, creates diversity and the unique contributions offered from His devotees.

This allows them to express their own independent unique character and personality that is eternally existing in a "two-sided" cooperative voluntary reciprocal relationship with Krsna. 

Krsna (God) is the source of all things, nothing can operate or exist separate from Krsna, as said above, not even a blade of grass can move without the will of Kṛṣṇa, who is the Supreme Personality of Godhead and cause of all causes. 

So, how are the individual jiva-souls (devotees) able to freely express themselves and make their own choices when everything is under Krsna's absolute control, including free will and past, present and future? 

Their are many who do not understand the ultimate goal of "devotional service" or the real meaning of "surrender." 

Both the above does not mean to be Krsna's mindless slave, puppet and "yes" men and women. They foolishly believe that when one enters the Kingdom of God (the Vaikuntha planets and Goloka Vrindavana) and surrender to Krsna, they have to give up their free will and now be always told what to do and think, without any need to provide personal contributions, endeavours and offerings chosen uniquely by each individual devotee.

This so called mindless "surrender" is really practising impersonalism, which is the pathway leading to spiritual suicide, it extinguishes the devotees individual identity, personality, and the God given ability to express themselves in the way they choose serving Krsna in the spiritual world.  

Therefore, freedom of self-expression (free-will) must exist in the spiritual world so the devotees (the eternal individual jiva-souls) have a "two-sided" cooperative reciprocal forever expanding relationship with Krsna. 

Such unique distinctive independence eternally experienced by the individual jiva-souls, is allowed by Kṛṣṇa to permit and encourage voluntary self-expression in a service the devotees choose to do, and not chosen for them by Krsna.××.
