Any writer on the Religion of the Sikhs must necessarily be greatly indebted to Mr. Max A. Macauliffe's unique work on the subject, The Sikh Religion Its Gurus, Saints, and Authors. My special thanks are due to the Oxford Univer sity Press for kind permission to quote extensively from the translation of the hymns. The details of the lives of the Gurus are taken from the same source, together with the English version of the prophecies by Teg Bahadur and Gobind Singh.
