The fellowship of those who bear the mark of pain: who are the members of this Fellowship? Those who have learnt by experience what physical pain and bodily anguish mean, belong together all the world over; they are united by a secret bond.

Impart as much as you can of your spiritual being to those who are on the road with you, and accept as something precious what comes back to you from them.

To affirm life is to deepen, to make more inward, and to exalt the will-to-life. At the same time the man who has become a thinking being feels a compulsion to give every will-to-live the same reverence for life that he gives to his own. He experiences that other life as his own. He accepts as being good: to preserve life, to raise to its highest value life which is capable of development; and as being evil: to destroy life, to injure life, to repress life which is capable of development. This is the absolute, fundamental principle of the moral, and it is a necessity of thought.

Not one of us knows what effect his life produces, and what he gives to others; that is hidden from us and must remain so, though we are often allowed to see some little fraction of it, so that we may not lose courage.

To educate yourself for the feeling of gratitude means to take nothing for granted.

The great enemy of morality is indifference.

If you study life deeply, its profundity will seize you suddenly with dizziness.
