The pure mind, which is the source of all things, shines forever with the radiance of its own perfection. But most people are not aware of it, and think that Mind is just the faculty that sees, hears, feels and knows. Blinded by their own sight, hearing, feeling and knowing, they don't perceive the radiance of the source. If they could eliminate all conceptual thinking, this source would appear, like the sun rising through the empty sky and illuminating the whole universe.
