Why must the impersonalist doctrine be absolutely rejected?

The impersonalist doctrine, developed by all those who believe that God is only pure spirit and has no human form, must be absolutely rejected, for it leads the incarnate soul to perdition and perpetual suffering.

An impersonalist is one who refuses to believe that God has a totally spiritual body in human form. For them, God is an Eternal Spiritual Being without form, because He is only pure energy. This belief is widespread among believers on earth.

All those who uphold the impersonalist doctrine must become a tree in their next life.

Unlike the impersonalist, the personalist knows that God, the Supreme Spiritual Person, in His personal, primordial, original, infinite, and absolute form, has a totally and solely spiritual body, the form of which He gave to mankind.

Genesis 1:26-27 states, God said: Let Us make man in Our image, according to Our likeness. So God created man in His own image; in the image of God He created him; male and female He created them.

Krishna, the Supreme Personality of Godhead, gave man a body whose form is identical to His own. Lord Krishna's form is entirely and purely spiritual, of indescribable beauty, full of absolute knowledge, of the most perfect bliss, of complete truth, of sublime, infinite, absolute, and eternal reality.

Krishna, the Supreme Eternal, says of Himself: My spiritual and absolute body resembles the human form in every way, but it is not a material body. It is inconceivable. I am not compelled by nature to accept a particular type of body; I choose the form in which I appear of My own free will. My heart is also spiritual, and I am always full of benevolence towards My devotees. Thus, one can discover in My heart the path of devotional service, intended for holy beings, while I have rejected irreligion and non-devotional activities; they hold no attraction for Me. Because of all these divine attributes, prayers are generally addressed to Me under the name of Rishabhadeva, the Supreme Lord, the best of all living beings.

Krishna comes to earth at regular intervals to protect His devotees, destroy demonic miscreants, and restore spirituality. During His stay in Vrindavana, a region of India and a replica of the kingdom of God, He developed sublime pastimes and took the opportunity to spread His sublime teachings. Krishna descended from His kingdom with His celestial entourage, including His first plenary emanation, Balarama, who there plays the role of elder brother.
