Happiness, true happiness, is an inner quality. It is a state of mind. If your mind is at peace, you are happy. If your mind is at peace, but you have nothing else, you can be happy. If you have everything the world can give - pleasure, possessions, power - but lack peace of mind, you can never be happy.

A lot of suffering is just getting rid of dross in yourself, and lingering and hanging in the darkness is often - I say this against myself - a failure of imagination, to imagine the door into the light.
