“Descend from the infinite to the infinitesimal. Long before... observation had begun to penetrate the veil under which Nature has hidden her mysteries, the restless mind sought some principle of power strong enough and of sufficient variety to collect and bind together all parts of a world. This seemed to be found, where one might least expect it, in abstract numbers. Everywhere the exactest numerical proportion was seen to constitute the spiritual element of the highest beauty.”

Origins Reconsidered: In Search of What Makes Us Human (1992)

Bodhi Tree lecture (1999)
Context: We join together to earth the power of the season and to slip between the worlds, the voices saying to every one of us, "Wake up, you are it, you are a part of the circle of the wise. There is no mystery that has not already been revealed to you. There is no power you do not already have. You share in all the love there is. The goddess awakens in infinite forms and a thousand disguises. She is found where she is least expected, appears out of nowhere and everywhere to illumine the open heart. She is singing, crying, moaning, wailing, shrieking, crooning to us, to be awake, to commit ourselves to life, to be a lover in the world and of the world, to join our voices in the single song of constant change and creation. For her law is to love all beings, and she is the cup of the drink of life. The circle is ever open, ever unbroken.

De la sagesse (1601)
Context: All Religions have this in common, that they are an outrage to common sense for they are pieced together out of a variety of elements, some of which seem so unworthy, sordid and at odds with man’s reason, that any strong and vigorous intelligence laughs at them; but others are so noble, illustrious, miraculous, and mysterious that the intellect can make no sense of them and finds them unpalatable. The human intellect is only capable of tackling mediocre subjects: it disdains petty subjects, and is startled by large ones. There is no reason to be surprised if it finds any religion hard to accept at first, for all are deficient in the mediocre and the commonplace, nor that it should require skill to induce belief. For the strong intellect laughs at religion, while the weak and superstitious mind marvels at it but is easily scandalized by it.
