NATTHĀ, BHĀĪ, a successor of the Udāsī saint Almast, was, during the time of Gurū Har Rāi, in Bengal to preach the message of Gurū Nānak. He made ḍhākā his headquarters and preached mostly in what now comprises Bangla Desh. At ḍhākā he built a Gurdwārā now called Gurdwārā Saṅgat Ṭolā. He also dug a well of which some remains still exist. He possessed a kind heart, but was short-tempered and had a rough tongue. When Gurū Tegh Bahādur visited ḍhākā during the late 1660's, some Sikhs complained to him of Bhāī Natthā's abusive nature. "This brother Natthā keeps calling us names. He does not spare even masands, exalted by the Gurū himself. He quarrels with everyone and keeps amity with none. He speaks foully." The Gurū sent for Natthā and said, "Natthā brother, everyone here has a complaint against you You abuse everybody. You take not their counsel. And you speak out what comes to your tongue." "They are fools sans all sense," answered the inveterate Bhāī Natthā. "I have never abused anyone." The Gurū laughed and told the Sikhs : "Mind not what he says. He has no malice in him. His words are harsh but his heart is pure. He is dyed in God's love. Do not be upset by what he says. Try to be pure-hearted like him."
