Individual human beings are so subtly developed through the centuries that it is strictly impermissible to compare any two men who are not contemporaries-that is to say are taken from two quite different times.

We have only to believe. And the more threatening and irreducible reality appears, the more firmly and desperately we must believe. Then, little by little, we shall see the universal horror unbend, and then smile upon us, and then take us in its more than human arms.

Love is the most universal, the most tremendous and the most mystical of cosmic forces. Love is the primal and universal psychic energy. Love is a sacred reserve of energy; it is like the blood of spiritual evolution.

To love is to approach each other center to center.

Isolation is a blind alley....Nothing on the planet grows except by convergence.

Evolution is gaining the psychic zones of the world... life, being and ascent of consciousness, could not continue to advance indefinitely along its line without transforming itself in depth. The being who is the object of his own reflection, in consequence, of that very doubling back upon himself becomes in a flash able to raise himself to a new sphere.

Is evolution a theory, a system, or a hypothesis? It is much more it is a general postulate to which all theories, all hypotheses, all systems must henceforward bow and which they must satisfy in order to be thinkable and true. Evolution is a light which illuminates all facts, a trajectory which all lines of thought must follow this is what evolution is.
