To elaborate on the question, I am assuming that in the beginning there was no Atma stuck in maya, is there any information on how the perfect Atma got stuck in Maya? Is my assumption wrong? To build on that, how can anything be eternal? Everything should have a start and end isn't it? Because something has to initiate first for the universe to be born, say big bang! and there are many theories on how the universe will end. Shouldn't there be something similar for brahman?
