There are two great fundamental problems common to all thought: (i) the problem of world- and life-affirmation and world- and life-negation, and (2) the problem of ethics and the relations between ethics and these two forms of man's spiritual attitude to Being.

Indian thought has greatly attracted me since in my youth I first became acquainted with it through reading the works of Arthur Schopenhauer. From the very beginning I was convinced that all thought is really concerned with the great problem of how man can attain to spiritual union with infinite Being. My attention was drawn to Indian thought because it is busied with this problem and because by its nature it is mysticism. What I liked about it also was that Indian ethics are concerned with the behaviour of man to all living beings and not merely with his attitude to his fellow-man and to human society.

To the question whether I am a pessimist or an optimist, I answer that my knowledge is pessimistic, but my willing and hoping are optimistic.

The ethic of Reverence for Life is the ethic of Love widened into universality.

The great fault of all ethics hitherto has been that they believed themselves to have to deal only with the relations of man to man. In reality, however, the question is what is his attitude to the world and all life that comes within his reach. A man is ethical only when life, as such, is sacred to him, and that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help. Only the universal ethic of the feeling of responsibility in an ever-widening sphere for all that lives - only that ethic can be founded in thought. ... The ethic of Reverence for Life, therefore, comprehends within itself everything that can be described as love, devotion, and sympathy whether in suffering, joy, or effort.

Altogether, Jesus never behaves like a man wandering in a system of delusions. He reacts in absolutely normal fashion to what is said to Him, and to the events that concern Him. He is never out of touch with reality.

Every start upon an untrodden path is a venture which only in unusual circumstances looks sensible and likely to be successful.

As a rule there are in everyone all sorts of good ideas, ready like tinder. But much of this tinder catches fire, or catches it successfully, only when it meets some flame or spark from outside, i.e. from some other person. Often, too, our own light goes out, and is rekindled by some experience we go through with a fellow-man. Thus we have each of us cause to think with deep gratitude of those who have lighted the flames within us.

I was convinced - and I am so still - that the fundamental principles of Christianity have to be proved true by reasoning, and by no other method. Reason, I said to myself, is given us that we may bring everything within the range of its action, even the most exalted ideas of religion. And this certainty filled me with joy.

The great secret of success is to go through life as a man who never gets used up. That is possible for him who never argues and strives with men and facts, but in all experience retires upon himself, and looks for the ultimate cause of things in himself.
