All the revealed canonized scriptures and texts of different religious and philosophical traditions carry in their sacred body the message of Primal Lord: Adi Guru. That is why Apostle Bhai Gurdas, Father of Sikh Philosophy, called Rsi Patanjali a Gurmukh because Rsi Patanjali spent his life time in exposition of Classical Yoga Philosophy. The goal of philosophy may be enlightenment or self-realization and the goal of religion God, but in the final experience God and Truth are the same Divine Essence. A comparative study of Yoga Mysticism of the Sikhs and the world religious traditions is a fascinating study, and this book is a modest attempt to define 127 Attributes of God, 316 concepts by quoting 93 texts and translating 128 Hymns of Guru Granth Sahib, 43 Hymns of Dasam Granth Sahib and 19 Hymns from Works of Bhai Gurdas.
