अपि च स्मर्यते
api ca smaryate
Sūtra translation
Moreover Smriti also speaks of him (i.e. of the prâjña Self as being the universal light).
Moreover that aspect of the prâjña Self is spoken of in Smriti also, viz. in the Bhagavad Gîtâ (XV, 6, 12), 'Neither the sun, nor the moon, nor the fire illumines that; having gone into which men do not return, that is my highest seat.' And 'The light which abiding in the sun illumines the whole world, and that which is in the moon and that which is in the fire, all that light know to be mine.'
