Sant Kabir was a poet saint and one of the four major poets of Bhakti Kala of Hindi literature. Kabirdas believed in one supreme god. His teacher, or Guru, was Ramananda, a Vaishnava Saint.
Kabir advocated human values such as non-violence, equality, complete devotion to the deity, courage to speak the truth, simplicity in conduct and life.
He believed in nirguna Brahman – absolute reality without attributes – of the Upanishads and asserted that Brahman alone is the ultimate self, who is variously called Rama or Allah.
