Zen does not confuse spirituality with thinking about God while one is peeling potatoes. Zen spirituality is just to peel the potatoes.

The Master said, 'When we see men of worth, we should think of equalling them; when we see men of a contrary character, we should turn inwards and examine ourselves.'

Be like water making its way through cracks. Do not be assertive, but adjust to the object, and you shall find a way around or through it. If nothing within you stays rigid, outward things will disclose themselves.

The only power fear has is the power you give it.

Nirvana or lasting enlightenment or true spiritual growth can be achieved only through persistent exercise of real love.

For every mistake that you learn from you will save thousands of similar mistakes in the future, so if you treat mistakes as learning opportunities that yield rapid improvements you should be excited by them. But if you treat them as bad things, you will make yourself and others miserable, and you won't grow.
