The science of Witchcraft is based on our ability to enter an altered state of consciousness we call "alpha." In alpha the mind opens up to non-ordinary forms of communication, such as telepathy, clairvoyance, and precognition. Here we also may [...] receive mystical visionary information that does not come through the five senses. In alpha the rational filters that process ordinary reality are weakened or removed, and the mind is receptive to non-ordinary realities.[...]
Alpha is the springboard for all psychic and magical workings. It is the heart of Witchcraft. [...] You must master it first before proceeding to any other spell, ritual, or exercise in this book. [...]
Mystics in every religious tradition speak of alpha states of consciousness and the lure of divine light, although they do so in their own metaphors and images. In their own ways they have learned how to enter alpha as they pray or worship. They have learned how to become [supposedly] enlightened.
