1991 0-7734-9681-5
A survey of the manuscripts and printed editions of Sefer Ha-Yashar, one of the most complex spiritual and religious phenomena in 13th-century Judaism. It is one of the most important treatises in the history of Jewish spirituality, in which ethics merges with mysticism. Deals with the concept of God, Creation and problems of Evil, the illustration of Man and his Soul, and the theme of Love and Fear of God and Devekut in Sefer Ha-Yashar.
