Indian man: Is there a basic conflict between a spiritual life and material living? How does the philosophy...?
Prabhupāda: No. Material life means eating, sleeping, mating and defending. This is material life. And spiritual life means something more than this. Just like animal life or human life. Animal life, the common formula is eating, sleeping, mating and defending. A dog also eats; a man also eats. A man also sleeps, and a dog also sleeps. The man also have sex life, and the dog also have sex life. The dog also defends in his own way, and man also defends in his own way, maybe atomic bomb. That is a different thing. But the defense, defense measure... These four principles are common between human being and animal. So advancement of these four principles is not human civilization. That is animal civilization. That is not human civilization. And human civilization means that athāto brahma jijñāsā, the Vedānta-sūtra says. The Vedānta-sūtra, first aphorism is athāto brahma jijñāsā: "Now it is the time for inquiry about the Brahman." That is human life. Without this inquiry, that is animal life. So that is material life and... So long one is not spiritually inquisitive, jijñāsu śreya uttamam, he is animal because he has got only these four principles: eating, sleeping, mating and defending. That's all. He must be inquisitive, "What I am? Why I am put into these miseries of life—birth, death, old, disease? Is there any remedy?" These things should be questioned. Then it is human life. Then it is spiritual life. Athāto brahma jijñāsā. This is the beginning of Vedānta. Brahma-jijñāsā: One should be inquisitive to understand what is Brahman. That is spiritual life.
