Bhatt Kal Sahar was a Gaur Brahmin poet in the court of Guru Arjan, whose 54 hymns are incorporated in Adi Granth.[1][2][3][4][5] The title Bhatt is given to learned Brahmins. Traditionally, Kal Sahar is believed to a collector of hymns of other Bhatts which were later incorporated into Guru Granth Sahib by Guru Arjan.
