You know of the disease in Central Africa called sleeping sickness. . . . There also exists a sleeping sickness of the soul. Its most dangerous aspect is that one is unaware of its coming. That is why you have to be careful. As soon as you notice the slightest sign of indifference, the moment you become aware of the loss of a certain seriousness, of longing, of enthusiasm and zest, take it as a warning. You should realize your soul suffers if you live superficially.

At that point in life where your talent meets the needs of the world, that is where God wants you to be.

Don't stop to ask whether the animal or plant you meet deserves your sympathy, or how much it feels, or even whether it can feel at all: respect it and consider all life sacred.

A good example has twice the value of good advice

We must fight against the spirit of unconscious cruelty with which we treat the animals. Animals suffer as much as we do. True humanity does not allow us to impose such sufferings on them. It is our duty to make the whole world recognize it. Until we extend our circle of compassion to all living things, humanity will not find peace.

The true worth of a man is not to be found in man himself, but in the colours and textures that come alive in others.
