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 Eternal Supreme, 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 (that is why it is never subject to hunger, thirst, or fatigue, and has no veins). 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 as Rsabhadeva, the Supreme Lord, the best of all living beings.
Krishna comes to earth at regular intervals to protect his devotees, annihilate 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 here plays the role of elder brother.
Walking in the forest of Vrindavana and addressing his elder brother Balarama, Krishna said, Dear Brother, of all of us you are the first, and your lotus feet are the object of worship by the celestial beings. Look at these trees, rich in fruit, which have bent down to worship your lotus feet. It seems as if they are striving to pierce the darkness that forces them to take the form of trees. Verily, the trees that grow on the earth of Vrindavana are not ordinary beings. Because in their former life they upheld the doctrine of impersonality, now they must endure this frozen condition. But now they have the good fortune to see you in Vrindavana, and they pray to advance still further in the path of spiritual life through contact with you. Trees are generally counted among the beings bathed in the darkness of ignorance. The impersonalist philosophers also live in this darkness, but now those among them who on this blessed earth have assumed the form of trees are dispelling it, taking full advantage of your presence. Although they are trees and animals, these inhabitants of Vrindavana proclaim your glories. They hold ready for you their best welcome, as is customary for great souls receiving other great souls. As for the earth, how pious and fortunate must it be for your lotus feet to leave their mark on its body.
The impersonalist doctrine must be absolutely rejected, for it leads the incarnate soul to perdition and perpetual suffering.
