The magnitude, complexity and depth of more than fourteen hundred pages of the verses of Divine love/wisdom, humanism, spiritualism, polity, sociology, psychology, astronomy and other genres of knowledge could not have been grasped without divine blessing. Only a creative, mystic philosopher could have accomplished this fete. Guru Granth Sahib is spiritual manifesto of the world. It is scripture of scriptures. It is the epitome of the wisdom of the sages, the social reformers, devotees and stead-fasts from different walks of life, linguistic and geographical backgrounds. It has been and is the code of conduct for millenniums. It is a synthesis of noble traditions of the sacred world. This spiritual heritage is the quintessence, thus alternate of all ‘Gospels’. In a society (world), which is suffering from hatred, jealousy, terrorism, inhumanism and above all paganism, Guru Granth Sahib has a message of Fatherhood of God and brotherhood of Man. It is the only hope for an oppressed globe, which can dispel darkness and bring an end to fanaticism, racism, war and destruction.
