Human form is considered the best means
Human form is considered the best. Best means the human form has got developed consciousness.
Lecture on SB 6.1.1-4 -- Melbourne, May 20, 1975: So what to do at the time of death? One has to change. Death means change of this body. The modern civilization, they do not know it. That is the first understanding of spiritual knowledge, that we change our body. I am spirit soul, every one of us, spirit soul, even the animals and the trees and plants and aquatics, any living being. There are 8,400,000 different forms of living being. Of all of them, the human form is considered the best. Best means it has got..., the human form has got developed consciousness. Developed consciousness means they can understand what is past, what is future, what is present. Especially to understand his position as spirit soul, to understand God, to understand what is His relation with God, and what he should do in that relationship—these things are understandable in the human form of life, not otherwise. We cannot invite dogs and cats to come here and hear about Śrīmad-Bhāgavatam. No. That is not possible. But a human being, he can hear. He can understand.
