All those who uphold the doctrine of impersonality will have to become a tree in their next life and will never be able to enter the spiritual world, much less the kingdom of God.
Who are they, what are they risking, and what will happen to them after their death?
Impersonalism is the belief in a spiritual God, certainly, but one made solely and entirely of pure spiritual energy. Impersonalists are therefore those believers from the monotheistic religions widespread on earth who refuse to believe that God, the Supreme Spiritual Being, also called “the Eternal,” has a totally spiritual body in human form. Moreover, the human form of humans comes from God.
Krishna, the Supreme Personality of Godhead, says: The Impersonal Supreme Being is a partial manifestation of my person, and no truth is superior to me.
This dazzling radiance, this absolute light that you contemplate (addressing his devotee, Prince Arjuna), know that it is none other than the radiance emanating from my body. This radiance is none other than myself. This radiance is an emanation of my spiritual energy. The radiance extends beyond the realm of my external energy (the material cosmos).
Impersonalists believe me to be formless, and claim that I borrowed my present form, the one I manifest today, solely to serve some purpose. But these speculators are in fact devoid of true intelligence. However erudite they may be in the Vedic texts (the Vedas, the original holy scriptures), they are ignorant of my inconceivable energies and the eternal forms of my person. The reason is that I reserve the right not to show myself to unbelievers, thanks to my internal power, which veils me from their eyes. Therefore, fools and senseless people do not know my eternal, unborn, and imperishable form.
The Impersonal Supreme Spiritual Being is a partial manifestation of Krishna, the Supreme Personality of Godhead, the Supreme Lord, realized in the absence of these complete potencies. It is the all-pervading aspect of neutrality. It is the only aspect of Godhead known to believers on earth.
This spiritual effulgence is limitless and immeasurable. It emanates from Krishna's original body, which gives form to his impersonal, omnipresent, infinite, and unfathomable aspect, which is the cause of the creation of the innumerable planets, each endowed with a specific life atmosphere.
In truth, the Impersonal Supreme Spiritual Being is the radiance emanating from Krishna's sublime transcendental body.
