These words are taken from Italian Witchcraft by Raven Grimassi:
There is a force which dwells in all things, which is called the Numen. The power of an object is the power of its Numen. This essence has, of its own accord, a definite consciousness. If you are in harmony with the Ways, then you may call upon any Numen which you desire, and it will assist you. This is but one aspect of Magickal rapport.
Know that all things of the same nature (or essence) are as links in a chain. Through one you may influence the other. By this law do we make use of clay puppets. Yet even the mind is linked by thoughts and has power to reach out on its own.
The substance of Magick is best controlled and directed through the use of ritual. Ritual attracts power and through repetition it is accumulated.
Certain channels of power are formed through ritual, which becomes a link to a desired response or contact. Thus do we make use of the secret signs, symbols and gestures (which are empowered). Repetition is necessary as well as consistency.
As Strega, we draw power down from the Moon and also do we draw power from Nature. The God and Goddess oversee our works, as do the Grigori. When our Magick does not produce the desired effects, it is because a greater power resists its power. This is often a sign that the nature of the Magick was improper. Yet it can be that another Strega works against you. If this becomes the matter, then seek this person out and resolve your differences.
Understand that you must always work in harmony with the phases of the Moon, under the blessings of the God and Goddess and in accordance with the laws and ways.
The Moon symbolizes the hidden things revealed in darkness. The night is the side of life which is unknown. The light of the Moon is subtle and active on hidden levels. So too is our Magick.
The powers which are obtained through the knowledge of the Old Ways are neither good nor evil,it is only the way in which you use them that is good or evil.
The mind is most receptive to the influence of power when the person is intoxicated or asleep (within two hours of awakening). This is true also of trance, which is induced through chant and dance.
The mind which dreams (the subconscious) is directly linked to the Moon Worlds (the Astral Realms) just as the mind which knows the daylight (the conscious mind) is directly linked to the Physical World. It is through the dream mind that the Moon Worlds are contacted. It is through the Moon Worlds that Magickal influences and Magickal forms, are created. These in turn, influence the Physical World.
It is the purpose of symbols to speak to the dream mind, and plant the Magickal seeds which will manifest. It is the purpose of rituals(and spells) to establish the patterns of power. These patterns are established to either draw upon power or to raise power (or both).
Magickal and ritual correspondences are incorporated to take advantage of the Numen qualities in objects, times of power, links to Deities, and states of consciousness (awareness).
The art of Magick is a blending of inner or personal power with that of the natural powers and divine powers.
