Speaking to the renewal of mystic fervour among seekers today, the book studies the spiritual masters of Jewish history whose teachings have brought inspiration and solace to generations of Jews from the prophets of the Bible and mystics of antiquity, to the Sufis and kabbalists of the Middle Ages, and the Hasidic masters of Eastern Europe. It presents the living teachers and their living teachings, their inner spiritual life with the divine, and their relationship of love with their disciples.
