There was darkness and there was light. And He chose light.
He didn’t have to choose light. He could have chosen an eternal wrestling match of light and dark. What greater pleasure can there be than the aroma of darkness struck down and transformed to a throne for light?
Nevertheless, he chose light. He chose to set a time for the obliteration of darkness, a time of pure and perfect light. And what does He have from that?
He needs nothing from that. That is the plan He so desired.

Re: M.M. "Which state of the plant gives G-D light? The plant needing the water or is satisfied with water or when the plant gets water." It seems at the right point (or moment?) it is all one and the same,.. the paradox of revealed good? And at this point does it even matter?
