Evolution is a light illuminating all facts, a curve that all lines must follow.

Is evolution a theory, a system, or an hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true.

Love is a sacred reserve of energy; it is like the blood of spiritual evolution.

If we are to be happy, we must first react against our tendency to follow the line of least resistance, a tendency that causes us either to remain as we are, or to look primarily to activities external to ourselves for what will provide new impetus to our lives.

To say that Christ is the term and motive force of evolution, to say that he manifests himself as 'evolver,' is implicitly to recognize that he becomes attainable in and through the whole process of evolution.
