Grounded in Indian philosophy, tattwa cards were used by the Hermetic Order of the Golden Dawn. Tattwa cards may be the greatest gift the Golden Dawn gave to the world. They have been used in meditation, scrying, astral projection, healing and more.
In the Golden Dawn, each student made their own tattwa Cards. Pictures of tattwa cards painted by famous Golden Dawn members including W. B. Yeats and Israel Regardie may be found online.
