Kabir was found in a lotus pond near Benaras by Neeru and his wife Neema who adopted him and named him Kabir (the Most High). He had a son, Kamal and a daughter, Kamali by Mata Loi. Though a Hindu by tradition, he was a Muslim by upbringing. He said he had been sent by the Lord himself. He was a weaver by profession. He died at Magahar, considered a damned place, and both Hindus and Muslims claimed the body.
Although, Ramanand Ji was his outer Guru, ultimately it was Kabir gave Ramanand Ji true knowledge. In fact, in the previous 3 ages, he revealed his names as: Sat Sukrit, Munindra and Karunamaya. In his present age birth, he mentions Jaidev and Namdev among lineage of his Gurus. He is revered even today by Hindus, Muslims and Sikhs alike. His verses are included in the 'Aadi Granth' of the Sikhs.
He is the first Perfect Master to have revealed the secrets of the entire creation to world at large (see his two verses, both entitled: "Kar Nainon Deedar"). He met with opposition from Pandits and Maulvis alike. Sultan Sikandar Lodi attempted to punish him by various means such as by drowning, by fire and by mauling under an elephant's feet. His verses, though encompassing the highest secrets of Sant-Mat, clearly remain close to the common man's heart even today. He often uses strong language to denounce the prevalent ritualism. Of his works are 'Bijak', 'Granthavali', 'Shabdavali' and 'Anurag Saagar'. The King of Benaras was among his disciples. He had a galaxy of renowned disciples such as: Dharamdas Ji, Mir Taqi, Ganaka Ji, Pipa Ji, Dhanna Ji, Sadana Ji etc.
Kabir was born in a weaver's family and later adopted by childless Muslim weavers named Niru and Nimma, who found him near Lahara Tara lake, adjacent to the holy city of Varanasi.
A Bhakti saint, who sang the ideals of seeing all of humanity as one, his name, Kabir, is often interpreted as Guru's Grace.
A weaver by profession, Kabir ranks among the world's greatest poets. In India, he is perhaps the most quoted author. The Holy Guru Granth Sahib contains over 500 verses by Kabir. The Sikh community in particular and others who follow the Holy Granth, hold Kabir in the same reverence as the other ten Gurus.
Kabir openly criticized all sects and gave a new direction to the Indian philosophy. This is due to his straight forward approach that has a universal appeal. It is for this reason that Kabir is held in high esteem all over the world. To call Kabir a universal Guru is not an exaggeration.
Kabir is also considered one of the early northern India Sants. One source for modern adaptations of Kabir's poetry is Robert Bly's The Kabir Book: Forty-Four of the Ecstatic Poems of Kabir.
Kabir is considered the first (with Nanak) Satguru of Sikh religion and Sant Mat tradition.
