Loving service to Krsna is not a one-way or one-sided affiliate of total supremacy or preeminence, no, there is always a choice by the jiva-souls of voluntarily participating.

Srila Prabhupada - "Love means two, there must be two, the lover and the beloved." (Lecture on BG Chapter 9 text 2-5, New York, Nov 23, 1966)

In Vaikuntha and Goloka Vrindavana personal voluntary expressions of loving exchanges are always encouraged by Krsna in His relationship with the jiva-souls that adds flavour, variety and mystery to their association with Krsna in Goloka-Vrndavana.

This means the Kingdom of God (Goloka-Vrindavana) is not a one-sided dominating realm devoid of personal expressions (free will) that denies personal unique contributions or offerings by the jiva-souls to Krsna that expand, enrich and flavour one's loving association with Krsna.

Loving service to Krsna and exchanges with Him cannot exist if there is only a one-sided affiliate of total supremacy or preeminence. 

The fact is genuine loving relations and service are based on free will which means loving exhanges between two, and is never a one sided dominating affair.

Free will only has meaning when the jiva-souls can express themselves in a two-sided relationship with Krsna.

Srila Prabhupada - "If you have no free will, then you are a stone. The stone has no free will. You want to be stone? Then you must have free will!" (August 5, 1976, New Mayapur France)

In other words, loving reciprocation is only possible between two, with each contributing to the relationship that expands the variety of nectarine mellows.

The word reciprocation only has meaning when there are two involved, NOT one.

Free will is eternally the constitutional make up of every marginal living entity (jiva-soul) and the foundation in all relationship with Krsna because free will gives the jiva-souls a voice.

Srila Prabhupada - ''Love means you take and you give also. Suppose if you love somebody and you simply take from him, but you don't give. Oh, do you think it is very good? No. It is not good. That is not love. That is exploitation. If I go on simply taking from you, and if I don't offer you anything, that is simply exploitation." (Lecture on BG Chapter 9 text 2-5, New York, Nov 23, 1966)

Srila Prabhupada - ''We have got the propensity to love. Love means somebody else. Love cannot be one or love cannot be executed by 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." (SB Canto 1 Chapter 2 text 6, Delhi, Nov 12, 1973)

Srila Prabhupada - ''The impersonalist philosophy is oneness, so how there be love with just one? Is it possible? Have you got any such experience that love means one? No. Love means two. There must be two, the lover and the beloved. Kṛṣṇa is already lover. He loves you so much that He's trying to get you back. That is Kṛṣṇa's attempt. "Please, My dear boy, or My dear friend, My dear servant." (SB Canto 2 Chapter 1 text 3, Paris, June 12, 1974)
