Prabhupāda: So God is cause of all causes. And in the Bhagavad-gītā it is explicitly said,
- ahaṁ sarvasya prabhavo
- mattaḥ sarvaṁ pravartate
- iti matvā bhajante māṁ
- budhā bhāva-samanvitāḥ
- (BG 10.8)
"I am the original source of everything. Everything is emanating from Me." Iti matvā, understanding like this, budhā. Budhā means those who are conversant, thoroughly in knowledge. Iti matvā bhajante māṁ budhā bhāva samanvitāḥ, in ecstasy, "Oh, here is the original cause of all causes." So in this way those who are advanced in knowledge, budhā, they engage themselves in the service of the original cause of all causes. He's the cause of all causes, but He has no cause. That is God. Anādir ādir govindam. He has no cause, but He's the cause of all life. That is God. Just like I am the effect, my father is the cause. Similarly, my grandfather is the cause of my father. My grandfather is the effect of the cause of great-grandfather. You go on searching out, searching out. So when you find out the original cause, that is God. That is the definition of God.
