„Anyway, the trick is simply this: No matter what happens, keep your heart open. Wide open.

To open your heart is to reduce your ego, and this is the only magic that is ever required to experience the naked truth.“

Dwells in hearts as open as all Space
Itself, who ask for nothing but the light
That rinses the heart of hate so that the stars
Above will be below when man has Love.“

That rinses the heart of hate so that the stars
Above will be below when man has Love.

„When seen as a whole, art derives from a person's desire to communicate himself to another. I do not believe in an art which is not forced into existence by a human being’s desire to open his heart. All art, literature, and music must be born in your heart’s blood. Art is your heart’s blood.“
