Quotes from Buddhadasa

True happiness consists in eliminating the false idea of 'I'.

What is the world full of? It is full of things that arise, persist, and cease. Grasp and cling to them, and they produce suffering. Don't grasp and cling to them, and they do not produce suffering.

Happiness is when there is no hunger or want at all, when we're completely free of all hunger, desire, and want.

Do work of all kinds with a mind that is void and to the voidness surrender all of the fruits.
