Book excerpt: The vision of Guru Nanak, the fifteenth-century founder of the Sikh faith, celebrated the oneness of the Divine that both dwells within and transcends the endless diversity of life. Guru Nanak's immaculate vision inspired the rich and inclusive philosophy of Sikhism, which is reflected in this exquisite and highly acclaimed translation of poems from the religion's most sacred texts: the Guru Granth Sahib, the principal sacred text of the Sikh religion, which consists of poems and hymns by Guru Nanak, his successors and Hindu and Islamic saints; and the Dasam Granth, a collection of devotional verses composed by the tenth Sikh Guru. Poetry from these highly revered texts is heard daily and at rites of passage and celebration in Sikh homes and gurudwaras, carrying forward the Sikh belief in the oneness and equality of all humanity.
