 During the Nineteen Day Fast, a period of the year during which Bahá'ís adhere to a sunrise-to-sunset fast, they meditate and pray to reinvigorate their spiritual forces.Movements which use magic, such as Wicca, Thelema, Neopaganism, and occultism, often require their adherents to meditate as a preliminary to the magical work.This is because magic is often thought to require a particular state of mind in order to make contact with spirits, or because one has to visualize one's goal or otherwise keep intent focused for a long period during the ritual in order to see the desired outcome.
