Born into a society caught in the throes of orthodoxy and ritualism and further crippled by child marriage, infanticide, and a rigid caste system, Guru Nanak was deeply spiritual from an early age. The outpouring of Nanak's faith evolved into the universal message of the omnipresence and existence of one God, of true love, equality and compassion, which appealed to Hindus and Muslims alike. Drawing upon the various myths and legends contained in anecdotal biographies and placing them in as precise a historical framework as possible, The Book of Nanak traces the chronology of the main events of Nanak's life.
