MANSUKH was, according to Purātan Janam Sākhī, a merchant of Lahore who, learning about Gurū Nānak from one of his customers Bhāī Bhagīrath, travelled with him to Sultānpur. There he remained in attendance on the Gurū for three years and learnt, as says the Janam Sākhī, to recite bāṇī, the sacred hymns. He is also said to have reduced some of these to writing as well. Returning to Lahore, he set up a saṅgat or fellowship of disciples there. Later he travelled with his merchandise to Siṅhaldvīpa (Ceylon) where his piety attracted the notice of Rājā Shivanābh, who became a devotee of Gurū Nānak when the latter visited Ceylon during his southern udāsī.
