Before there was light – there was the infinite invisible soul – the heart of all, the soul which felt such love!!! – now this soul/heart happens to be infinite – which means, lacking nothing – there is no manifestation, reality, multiple reality! darkness / light! that cannot be created! – so the Kabbalists teach us that what this soul/heart did was make a sequence (called seder-hishtalshulut, the chain-of-descent) firstly He made the space – a deep void (as the Bible tells us, it was deep, dark and confusing) and in this void he put in light – this light has many meanings – but ultimately what is important to understand is that we always have, and always will fluctuate
