the light which shines above this heaven

'Now the light which shines above this heaven, above all, above everything, in the highest worlds beyond which there are no higher, verily, that is the same as this light which is here within the person.'

'Chandogya Upanisad, Section 13, from The Principal Upanisads, translated from the Sanskrit by S. Radhakrishnan, 1953. This is the closest I've come to 'as above, so below', the only quote I thought I knew from The Upanishads, the oldest of old books. Tom, is it in here'!'!'
