MANSUKH was, according to Puratan Janam Sakhi, a merchant of Lahore who, learning about Guru Nanak from one of his customers Bhai Bhagirath, travelled with him to Sultanpur. There he remained in attendance on the Guru for three years and learnt, as says the Janam Sakhi, to recite bdni, the sacred hymns. He is also said to have reduced some of these to writing as well. Returning to Lahore, he set up a sangat or fellowship of disciples there. Later he travelled with his merchandise to Sinhaldvipa (Ceylon) where his piety attracted the notice of Raja Shivanabh, who became a devotee of Guru Nanak when the latter visited Ceylon during his southern udasi.
