In sacred literature, the Japji may be aptly compared with ‘the Gita and the New Testament. It is Guru Nanak’s most remarkable contribution that begins with Mool Mantra Ik Oankar Satnam… It is one of the products of those minds who have tasted God-consciousness and whose words beckon generation after generation of men to prepare themselves for the descent of the Divine into their lives. This long hymn is the epitome of Sikh religious philosophy and the rest of the Holy Book is an exposition of the thought contained in the Japji. Guru Granth Sahib, the Sikh Scripture, begins with the Japji.
