Baba Sri Chand, the eldest son of Guru Nanak Dev Ji, was born on Bhadoo Sidhi 9th sanmat 1551 to matta Sulakhni in Sultanpur. He lived in Barath village, near Dehra Nanak, Baba Sri Chand never married and later started the Udasi sect (one among the NanakPanthi sects). Though there several visible sects associated with NanakPanth today, the three main sects include, Udasi, Saehajdhari, and Sikhs (including Nihang, Nirmalae, and Kukae) [ref. Mahan Kosh]. Baba Sri Chand passed away on 15th Assu samnat 1668 at the age of 118.

Baba Gurditta Ji became the first disciple of Baba Sri Chand, who sent many GurSikhs in Udasi attires to preach and propagate Satguru's message in this world. Later there were four saewaks; namely, Ballu Hasna, Almast, Phulshah, and Gonda. Four popular branches emerged from these saewaks that are represented by four Matths (centres of worship). Along with these four branches, there are the following six blessed branches for a total of ten Udasi sects:-

Udasi attire includes "manjithi Cholla" (long dress), "gal kali Saeli" (black neck scarf), "hath Tumbha", and "Uchi Toppi" (high cap). Initially, the udasi did not cut their hair or beard, though such practices are prevalent today. However, Guru Granth Sahib is the holy scripture of all Udasi sects.

Baba Sarbjot Singh Ji Baedi from Una Sahib is a living member of Guru Nanak's family who organized the Gurmat Sangeet Samaelan together with Baba Sucha Singh of Gurudwara Gur Gayan Prakash.
