Egyptian Magic in Egyptian Magic by Florence Farr.

“Mild saintliness was by no means the ideal of the Egyptian Priesthood. Intense practical interest in the life of their country, and the ennobling of natural functions, drew a sharp contrast between them and the ascetics of India and Christendom. ‘Whatever your hand findeth to do, do it with your might,’ is a text that may well have come down to us from Ancient Egypt. The generative processes of Nature were honoured by them at special festivals—but at the same time the degradation of natural functions by excess was sternly reprimanded.” [via]
