Spellcraft is the practice of casting spells, the use of ritual words, gestures, objects and focused intention to bring about a desired change in the world by magical means. It is a defining activity of contemporary Wicca and modern Pagan witchcraft, and it draws on a long heritage of folk magic and cunning-craft practised across cultures for such everyday ends as healing, protection, love, prosperity and the warding off of harm. A spell typically combines several elements: a clear intention or aim; spoken words, often rhymed or repeated, that name and empower the working; symbolic objects and correspondences, candles, herbs, stones, colours, images, chosen for their traditional associations with the goal; and the raising and directing of the practitioner's will and energy toward the outcome, often within a ritually prepared and protected space.
Modern Wiccan and Pagan spellcraft is generally practised within an ethical framework that distinguishes it sharply from the popular image of harmful sorcery. Many Wiccans hold to a rule of harm, the counsel to work magic only in ways that harm none, and to a belief that the energy one sends out returns amplified, which together discourage coercive or malicious workings. Practitioners understand the efficacy of spells in varying ways, some as the direct working of a real magical force, others in largely psychological terms, the spell as a focusing of intention and a shaping of the practitioner's own mind and attention toward the goal, and many hold both understandings together. Distinct from the invocation and worship of deities that also feature in Pagan practice, spellcraft is the practical, results-oriented dimension of modern witchcraft, continuous with the folk-magical traditions from which much of it is consciously drawn.
