Attentiveness is the natural prayer of the Soul.

Just as our eyes need light in order to see, our minds need ideas in order to create.

Do not fear lest you should meditate too much upon Him and speak of Him in an unworthy way, providing you are led by faith. Do not fear lest you should entertain false opinions of Him so long as they are in conformity with the notion of the infinitely perfect Being.

I do not believe there is anything useful which men can know with exactitude that they cannot know by arithmetic and algebra.

You find yourself in the world, without any power, immovable as a rock, stupid, so to speak, as a log of wood.

Attentiveness is the natural prayer of the Soul.

When I touch a human hand, I touch heaven.
