Buddhadasa quotes:

Hell was OK, until some wise guy went to heaven and came back

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

The entire cosmos is a cooperative. The sun, the moon, and the stars live together as a cooperative. The same is true for humans and animals, trees, and the Earth. When we realize that the world is a mutual, interdependent, cooperative enterprise -- then we can build a noble environment. If our lives are not based on this truth, then we shall perish.

Those who read books cannot understand the teachings and, what's more, may even go astray. But those who try to observe the things going on in the mind, and always take that which is true in their own minds as their standard, never get muddled. They are able to comprehend suffering, and ultimately will understand Dharma. Then, they will understand the books they read.

To believe straight away is foolishness, to believe after having seen clearly is good sense. That is the Buddhist policy in belief; not to believe stupidly, or to rely only on people, textbooks, conjecture, reasoning, or whatever the majority believes, but rather to believe what we see clearly for ourselves to be the case. This is how it is in Buddhism.

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.

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

The practice is to make the non-arising of grasping and clinging absolute, final, and eternally void, so that no grasping and clinging can ever return. Just that is enough. There is nothing else to do.

All beings may dance at ease in the breeze with minds left silent by laying to rest all things.

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