Is everything the "will" of Krsna?

In one sense, not always because the jiva-souls have their independence.

However, ultimately EVERYTHING is the "will of Krsna", as Bhagavad Gita says- 

"Not a blade of grass moves without the will of the Lord". 

Even having free will is only possible if Krsna allows it. This is because Krsna is the Supreme Personality of Godhead and cause of all causes.

Krsna always allows "free will" because it allows voluntary contributions, self expression and a "two-way" relationship.

Therefore having "free will" is also the eternal constitutional make up of EVERY "marginal living entity", and is the foundation for ALL jiva-soul's relationship with Krsna that allows unique individual offering and exchanges.

Srila Prabhupāda – ''Love means a relationship between "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". (August 9, 1976, Tehran)

The Sun-disc and the sun-rays CANNOT exist separately from each other, similarly Krsna cannot exist separately from His living entities (parts and parcels) and the living entities CANNOT exist without Krsna.

Each "jiva-soul" (marginal living entity) is a one of a kind independent individual with their own unique personality and character different from other personalities including Kṛṣṇas.

No two individual jiva-souls are the same, and no jiva-souls can EVER become God (Krsna or Visnu).

Loving devotional service to Krsna is ALWAYS based on a "two-way" voluntary exchange of personal feelings manifesting as loving acts of reciprocation between Kṛṣṇa and His devotees, who voluntarily contribute their own unique expressions (offerings) of devotional service to Him as the real act of surrendering to Krsna's will that does not deny the "free will" of each jiva-soul.

Actions expressed in a "one-way" domineering forceful mood from a "so called God" in His Kingdom that does not allow personal voluntary contributions from the individual jiva-souls in a "two-way" exchange of feelings, is dangerous impersonalism.

Personalism means a "two-way" relationship that includes voluntary loving exchange of feelings that expands, enriches and multiplies loving affection, sentiment and exchanges between the jiva-souls and Krsna.

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, personally. 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)

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)

Srila Prabhupada - "Free will means that you can act wrongly. That is free will. Unless there is chance of doing wrong or right, there is no question of free will. Where is free will then? If I act only one sided, that means I have no free will. Because we act sometimes wrongly, that means free will." (Philosophy Discussions with Rene Descartes)

Srila Prabhupada – “So everyone can know that independence means one can use it properly, one can misuse it. That is independence. If you make it one way only, that you cannot become fall down, that is not independence. That is force.” (Mayapur, June 20, 1973)

Srila Prabhupada - “Service in the spiritual world is always voluntary. Some devotees want to serve Krsna as flower; so they become flower there. If I want that, to be a flower I shall lie down at the lotus feet of Krsna, then he becomes flower, voluntarily, and he can change his, from flower to human body. That is spiritual life. There is no restriction. If some devotee wants to serve Krsna as cow, he serves Krsna as cow, as calf, as flower, as plant, as water, as ground, field, or as father, as mother, as friend, as beloved, anything. It is inconceivable, yet a fact". (Srimad Bhagavatam 6.1.1-4 - Melbourne, May 20, 1975)
