Humanity has been sleeping-and still sleeps-lulled within the narrowly confining joys of its little closed loves. In the depths of the human multitude there slumbers an immense spiritual power which will manifest itself only when we have learnt how to break through the dividing walls of our egoism and raise ourselves up to an entirely new perspective, so that habitually and in a practical fashion we fix our gaze on the universal realities.

Specialisation paralyses, ultra-specialisation kills. Palaeontology is littered with such catastrophes.

My starting point is the fundamental initial fact that each one of us is perforce linked by all the material organic and psychic strands of his being to all that surrounds him. . . . If we look far enough back in the depths of time, the disordered anthill of living beings suddenly, for an informed observer, arranges itself in long files that make their way by various paths towards greater consciousness.

Love is the most powerful and still most unknown energy in the world.

The world can no more have two summits than a circumference can have two centres.

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

Energy is the measure of that which passes from one atom to another in the course of their transformations. A unifying power, then, but also, because the atom appears to become enriched or exhausted in the course of the exchange, the expression of structure.
