Do what you have to do resolutely, with all your heart. The traveler who hesitates only raises dust on the road.
Master your thoughts. Any thought goes on inside your mind. Watch for a few minutes and you will be surprised: the mind seems to be crazy! It jumps from one thought to another thought for no reason at all.
Be quiet, and loving and fearless. Three things Buddha says: Be quiet—learn to be silent more and more—and loving, because if your silence is not loving it will make you insensitive. Then your silence will be that of a cemetery—dull, dead.
Zazen means just sitting doing nothing. The first thing to do is learn sitting, a deep restfulness. Become a pool of rest, not even ripples of desire, going nowhere, no ambition—not even for God, not even for nirvana.
