Nevertheless, the auras associated with temporal-lobe seizures continue to have mystical virtue. The auras have been described as similar to satori – in the Zen Buddhist tradition, a flash of sudden enlightenment, the first step toward achieving nirvana. Mystics, monks, saints and artists have experienced seizure-like auras: St. Paul, on a journey to Damascus, converted to Christianity after seizure-like experience in which the Lord spoke to him in a blinding flash of light. Joan of Arc reported ecstatic moments when she saw visions of angels. During his seizures, Fyodor Dostoyevsky experienced a sense of ecstatic well-being and transcendent happiness; Alfred, Lord Tennyson had mystic visions.
