Human form of life is meant for understanding the original cause of all causes. That is human form of life. Inquisitiveness. And others, less than human being, just like lower animals—cats and dogs, not to speak of the trees and plants, they are standing in one place; and other living beings, even the insects, birds, beasts—they haven't got sufficient intelligence. . . (aside:) No, this water, drinking. . . .sufficient intelligence to understand "What I am? Why I am suffering?" Everyone is suffering. That's a fact. The whole struggle for existence is going on.
Just like just now two big directors of this Dai Nippon Company came to see me. We have got business with them. So they are meeting so many problems for printing work. They are maintaining about 200,000 people to carry on their business, huge establishment, huge responsibility. But there are problems also. So this material world is full of problem. One who understands, he is called sura, or civilized man; and one who does not understand, he is called asura. Asura, not sura. Āryan, non-Āryan. So amongst the suras, those who can understand the problems of life, there is a system which is called religion. And what is the purpose of religion? Religion is to understand what is God. That is religion. Dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19).
