The planes below [the Supermind, from the Overmind to the Higher Mind] are of the spiritual consciousness but when there is a dynamic action from them, it is always a mixed action, not an action of pure knowledge but of knowledge subduing itself to the rule of the Ignorance, the cosmic necessity in a world of Ignorance. If their action was that of the full Knowledge, there would be no need of any supramental descent.
