Initially named Balu, he travelled with his elder brother Alu, also known as Bhai Almast, to receive teachings from Guru Arjan in Amritsar in 1604. Balu devoted himself to serving the Guru, and later accompanied Guru Hargobind on his chases, always wearing a smile that earned him the nickname "Hasna," meaning the laughing one. At the request of Guru Hargobind, Bhai Balu Hasna joined Baba Gurditta, the Guru's eldest son and spiritual successor of Baba Sri Chand, the founder of the Udasi sect.
