Guru Nanak’s Spiritual beliefs and practices, based on his direct experience of God, were profoundly transformational. He brought the path to enlightenment closer to the masses by his use of a language that they understood. His monotheism, coupled with his emphasis on the pursuit of divinity while living the life of an ordinary householder, was a significant departure from the prevailing beliefs in renunciation, pilgrimage, and other rituals. This book simplifies the Guru’s core spiritual message for the modern reader. The author, at the outset, enunciates the spiritual foundation of the Guru’s worldview and his conception of reality, including the nature of God. Japji Sahib, a foundational religious text, is presented in its original form together with an English translation and an in-depth commentary. The book concludes with a representative selection of the Guru’s hymns.
