What to read after Nanak?

Guru Nanak, the founder of the Sikh religion, walked the earth to restore love and humanity lurking in the doldrums. His early communion with the Ultimate drew him to far-fetched places to inculcate the scent of unity and equality among people. He sang the divine praises along the way and persuaded people towards the spiritual essence of the Lord. He made an intriguing manifestation that the Lord is One and there exists no other besides Him. Most of what Nanak professed was apparently derived from the Ultimate. As mentioned in the Janamsakhis, he often directed his companion Mardana to play on his rabab as he vividly sang the Bani or Divine Word descending upon him from the skies. With an unrelenting desire to spread enlightenment among the masses, he became an itinerant preacher to eradicate the upsurge of erroneous beliefs and the moss of differences propelled by caste and creed.
This exquisitely illustrated book explores the life of Guru Nanak at length and offers an insight into his timeless teachings which are marvelously ingrained in his divine hymns - the Japji, Asa di Var and Barah-maha.
