The Bhagats whose Bani has been included in Guru Granth Sahib belong to the period stretching from twelfth century CE to the seventeenth century. After reading and analysing the Bani of these Bhagats as recorded in Guru Granth Sahib, it becomes amply clear that all of them were the worshippers and votaries of One God. They preached the Oneness of God and exhorted the people to worship Him alone. Initially some Bhagats believed in idol worship and multiple gods but by the time they orated the bani that is incorporated in Guru Granth Sahib, they had realized the oneness of God. Very little is known about the lives of some of these Bhagats.
Details of the Bhagats Sahiban
Guru Arjan Dev ji, the 5th Guru of the Sikhs, included in Siri Guru Granth Sahib ji; the hymns of the Gurus, but also these select few holy man, whose utterances improved the spirito-religious, social & ethical life of the masses. If he included the hymns of Bhagat Pipa, a King, he also included the hymns of Bhagat Namdev, a Calico printer, and Bhagat Ravidas, a Cobbler, in the same way, irrespective of social divides such as caste. This unique approach had never previously been seen, and mankind is indebted to him for this.
