 Although the Bahá 'í teachings have a strong emphasis on social and ethical issues, there exist a number of foundational texts that have been described as mystical. The Seven Valleys is considered Bahá'u'lláh's "greatest mystical composition." It was written to a follower of Sufism, in the style of `Attar, The Persian Muslim poet, and sets forth the stages of the soul's journey towards God. It was first translated into English in 1906, becoming one of the earliest available books of Bahá'u'lláh to the West. The Hidden Words is another book written by Bahá'u'lláh during the same period, containing 153 short passages in which Bahá'u'lláh claims to have taken the basic essence of certain spiritual truths and written them in brief form.
