Kabir ji was a 15th-century Indian mystic poet and saint, whose writings influenced Hinduism's Bhakti movement and his verses are found in Sikhism's scripture Guru Granth Sahib. His early life was in a Muslim family, but he was strongly influenced by his teacher, the Hindu bhakti leader Ramananda.
Kabir is known for being critical of both Hinduism and Islam, stating that the former was misguided by the Vedas, and questioning their meaningless rites of initiation such as the sacred thread and circumcision respectively. During his lifetime, he was threatened by both Hindus and Muslims for his views. When he died, both Hindus and Muslims he had inspired claimed him as theirs.(There was dispute whether to cremate or bury his corpse).
Kabir suggested that True God is with the person who is on the path of righteousness, considered all creatures on earth as his own self, and who is passively detached from the affairs of the world. To know God, suggested Kabir, meditate with the mantra Rāma, Rāma.
Kabir's legacy survives and continues through the Kabir panth ("Path of Kabir"), a religious community that recognises him as its founder and is one of the Sant Mat sects. Its members are known as Kabir panthis.
The famous gurbani by Bhagat kabir ji from Guru Granth sahib is Gagan Damama Baajooh pariho nishaan-e-ghao, khet jo maandyo surma aab jujhan ka tao, Sura so pahchaniye jo lare deen ke het, purja purja kate marhe kabho na chhade khet
