Why is it that so many people are so unaware of their own higher existence? The answer is that their faculty of awareness itself is that spiritual existence. Whatever they know, people know through the consciousness within them. That in them which knows anything is their divine element. The power of knowing--whether it be a thought that is known, a complex of thoughts such as memories, a thing such as a landscape--is a divine power for it derives from the higher self which they possess.
