It may then seem that you had something very precious and lost it, or your mind may convince you that it was all an illusion anyway. The truth is that it wasn't an illusion, and you cannot lose it. It is part of your natural state, which can be obscured but can never be destroyed by the mind. Even when the sky is heavily overcast, the sun hasn't disappeared. It's still there on the other side of the clouds.

Eckhart Tolle
