In studying the Way, realizing it is hard;
once you have realized it, preserving it is hard.
When you can preserve it, putting it into practice is hard.

How can you come to know yourself? Never by thinking, always by doing. Try to do your duty, and you’ll know right away what you amount to. And what is your duty?
Whatever the day calls for.

Breathing in, be one with your own breath.
Breathing out, be one with your own breath.

To know the nature of the world, don’t study fine-bound books.
Infinitely more important than the answers are the questions,
the choice of them, the inner form of them.

Whenever the light of civilization falls upon you with a blinding power, then go into the wilderness. Go to the mountains. The wilderness and mountains are places to hold you. Let the cities become a memory. Let the wilderness and mountains take hold of you. They will give you good red blood. You will become full of spirit. You will soon behold all with a peaceful soul. There is something in the very name of the wilderness that charms. It soothes the spirit. This is where you will find umbalakiki.

If adventure has a final and all embracing motive it is surely this: we go out. Because it is our nature to go out, to climb the mountains and sail the seas, to fly to the planets and plunge into the depths of the oceans. By doing these things we touch something outside or beyond, which strangely seems to approve our doing them. We extend our horizon, we expand our being, we revel in a mastery of ourselves which gives an impression, mainly illusion, that we are masters of our world. This is umbalakiki.
