Bhagat Kabir ji
Bhagat Kabir (Gurmukhi: ਭਗਤ ਕਬੀਰ) (1441-1518)* was a Devotee, Saint and Gurmukh born in Uttar Pardesh, India. He was a monotheist and follower, probably founder, of Gurmat. He was a Muslim. There are 227 Padas in 17 ragas and 237 slokas of Kabir in Guru Granth Sahib. He is revered by Hindus, Muslims and Sikhs, some Sikhs even use the word Guru in reference to Kabir. Like other Devotees, Kabir did not believe in Ritualism, the worshiping of Dieties, Brahmanism or the Caste System. Kabir played the role of a teacher and social reformer by the medium of his writings. Bhagat Kabir guided Gurmat to Ramanand, whom he adopted as worldly guru. The Kabirpanthi sect which follow the teachings of Kabir, referring to him as their guru.
Sikhs also follow the teaching of Kabir, as in Gurmat, Kabir, Nanak, Ravidas, Bhatts all are same and all are treated as Guru and Sikhs bow before Guru Granth Sahib which include the teaching of many who had similar thoughts about God.
