When humans truly discover the power of love, it will prove more important than the harnessing of fire.

The most satisfying thing in life is to have been able to give a large part of one's self to others.

To love is to approach each other center to center.

The idea is that of the earth not only becoming covered with myriad grains of thought, but becoming enclosed in a single thinking envelope so as to form, functionally, no more than a single vast grain of thought on the sidereal scale, the plurality of individual reflections grouping themselves together and reinforcing one another in the act of a single unanimous reflection...A new domain of psychical expansion- that is what we lack. And it is staring us in the face if we would only raise our heads to look at it.

We are not human beings having a spiritual experience; we are spiritual beings having a human experience.

Someday, after mastering the winds, the waves, the tides and gravity, we shall harness for God the energies of love, and then, for a second time in the history of the world, man will have discovered fire.

This fundamental discovery that all bodies owe their origin to arrangements of single initial corpuscular type is the beacon that lights the history of the universe to our eyes. In its own way, matter obeyed from the beginning that great law of biology to which we shall have to recur time and time again, the law of "complexification."
