The spell is at the heart of folk magick. it is simply a ritual in which various tools are purposefully used, the goal is fully stated (in words, pictures or within the mind) and energy is moved to bring about the needed result.
Spells can be as simple as reciting a short chant over a fresh rose while placing it between two pink candles in order to draw love; forming and retaining an image of the needed result in the mind; or placing a quartz crystal in a sunny window for protection purposes.
To perform effective magick - three necessities must be present: The Need, the Emotion and the Knowledge. The Need, though personal should not be of a selfish or manipulative nature. The Emotion should be positive, devoid of any malice or negativity. The Knowledge should have been obtained from a dedication to the Craft, and a commitment to study and learning.
It has been said that magick was the first religion, a dedication to and worship of nature. If you lovingly utilize the forces of nature to cause beneficial change, you also become one of them. Such were the ways of the women of the communities; the herbalists, healers, midwives and counselors.
It is these powers that have been personified as Goddesses and Gods. Attuning with them is a spiritual experience and is the basic of all true religion.
