Lower Manas.

The Lower Manas is an emanation from the Higher Manas, and is of the same nature as the Higher. This nature can make no impression on this plane, nor receive any: an Archangel, having no experience, would be senseless on this plane, and could neither give nor receive impressions. So the Lower Manas clothes itself with the essence of the Astral Light; this astral envelope shuts it out from its Parent, except through the Antahkarana which is its only salvation. Break this and you become an animal.
