Kabir (1398-1518) was a well-known Indian mystic poet and saint. His writings influenced Hinduism's Bhakti movement, and his verses are found in Sikhism's scripture Guru Granth Sahib, the Satguru Granth Sahib of Saint Garib Das. Kabir's poetic personality has been variously defined by the religious traditions that revere him, and the same can be said for his hagiography. For Sikhs he is a precursor and interlocutor of Nanak, the founding Sikh Guru (spiritual guide). Muslims place him in Sufi (mystical) lineages, and for Hindus he becomes a Vaishnavite (devotee of the god Vishnu) with universalist leanings. But when one goes back to the poetry that can most reliably be attributed to Kabir, only two aspects of his life emerge as truly certain: he lived most of his life in Banaras (now Varanasi), and he was a weaver, one of a low-ranked caste. His humble social station and his own combative reaction to any who would regard it as such have contributed to his celebrity among various other religious movements and helped shape the Kabir Panth, a sect found across northern and central India that draws its members especially, but not exclusively, from the Dalits. The Kabir Panth regards Kabir as its principal guru or even as a divinity-truth incarnate. The broad range of traditions on which Kabir has had an impact is testimony to his massive authority, even for those whose beliefs and practices he criticized so unsparingly. From early on, his presence in anthologies of North Indian bhakti (devotional) poetry is remarkable.
