Overmind is a creator of truths, not of illusions or falsehoods: what is worked out in any given overmental energism or movement is the truth of the Aspect, Power, Idea, Force, Delight which is liberated into independent action
This passage delivers Aurobindo’s foundational ontological claim about Overmind: it produces genuine partial truths through the independent liberation of cosmic powers, distinguishing it from the planes of illusion and falsehood below it.
