Physics has always looked at the matter (or energy) as the source of everything that surrounds us. But when it confronted with the origin of the cosmos, the first moments of creation, begins to assume a range of issues beyond itself.
Indeed, even the modern cosmological theories face the abyss of the original zero. Physics tells us that space and time are products of that first explosion, says us that even non-physical dimensions of existence have been created from that mathematical zero. And when we ask about the origin of that zero simply warns us that the question is meaningless.
But the question strikes our mind and strives to make itself heard.
Our intuition and the knowledge of those people who have seen beyond the phisical senses tell us the opposite: matter and energy are the effect (not cause) of other dimensions that existed before them.
Sri Aurobindo said us that consciousness is the Ariadne thread that runs through these dimensions and that allows their existence. He talked us about Sat-Chit-Ananda...
Yes, consciousness is the beginning and the first motor.
Consciousness, that's to say, God Himself.
