The thinking (person) must oppose all cruel customs, no matter how deeply rooted in tradition and surrounded by a halo. When we have a choice, we must avoid bringing torment and injury into the life of another.

Everything deep is also simple and can be reproduced simply as long as its reference to the whole truth is maintained. But what matters is not what is witty but what is true.

Anyone who has accustomed himself to regard the life of any living creature as worthless is in danger of arriving also at the idea of worthless human lives.

We need a boundless ethic, one which will include the animals, too. Until we extend the circle of his compassions to all living things, we will not find peace.

At times our own light goes out and is rekindled by a spark from another person. Each of us has cause to think with deep gratitude of those who have lighted the flame within us.

For those who sincerely seek the truth should not fear the outcome.

In the same way as the tree bears the same fruit year after year, but each time new fruit, all lastingly valuable ideas in thinking must always be reborn.
