Now what is the nature of that origin? He is a stone or living entity? Because we have got two experiences, matter and life. A stone may be very big, but it has no life. But a small ant, although it is very small, it has got life, movement. It has got his independence of moving. That is called life. So if somebody, God or whatever you say, is the origin of everything, then what is the nature of that origin? Is He, is it like a stone or having life force? Naturally we can experience that without God being living, how the living entities are coming?
We have got experience that I am a living entity, I am coming out of my father who is also living entity. He is coming of his father, he is also living entity. So how the origin of everything can be a stone-like chunk? No. This is logic. This is philosophy. Therefore Bhāgavata says that janmādy asya yato 'nvayād itarataś cārtheṣv abhijñaḥ [SB 1.1.1]. Abhijñaḥ means He is full of consciousness, knowledge. Sat cit. Cit means He is living. He is not like a dead stone. That cannot be, because we have no experience that from dead stone life is coming.
