Non-being simply implies that the Being and everything else is held back. It is not an absence but a state of infinite possibilities yet not released like all the colours are held back in the white and the white itself is held back in the black. It is like the tree waiting in a seed. Or a book waits in the heart of the author. This is Non-being.
But once the stir of creation begins, the author appears. He is the same, as Non-being and Being, two poises of One Reality just as the person before the urge to write and after he has the urge to write are not two different beings. The writing itself is the becoming. It is the Author expressing himself, releasing all that was held back within his heart. Creation is the extension or the objectivisation of the Creator. Being is becoming, the Creator flows in His creations.
