These words are taken from Italian Witchcraft by Raven Grimassi:
We live upon the Earth because we are not prepared to live in the ways of the spirit. We are not physical beings, and this is why physical life is often difficult.
It is not our way to disregard the physical, for we dwell within it. So it is best to live in harmony with the world. But for us to become involved in the physical so as to disregard the spirit is likewise harmful. This binds us to rebirth, and to unhappiness.
A Strega respects life and all living things. Life must not be taken without necessity. The purpose of physical life is to learn the higher ways of spirit through knowledge of the lower and to prepare our spirit for the existence for which it was created.
