We must move from consciousness to its hidden reality, the mind-essence which is alone true consciousness because it shines by its own and not by a borrowed light. When we cease to consider Mind as this or that particular mind but as all-Mind; when we cease to consider Thought as this thought or that but as the common power which makes thinking possible; and when we cease to consider this or that idea as such but as pure Idea, we apprehend the absolute existence through profound insight. Insight, at this stage, has no particular object to be conscious of. In this sense it is a Void. When the personal mind is stripped of its memories and anticipations, when all sense-impressions and thoughts entirely drop away from it, then it enters the realm of empty unnameable Nothingness. It is really a kind of self-contemplation. But this self is not finite and individual, it is cosmic and infinite.
