UDASI, an ascetical sect of the Sikhs founded by Sri Chand (1494-1629), the elder son of Guru Nanak. Udasi is derived from the Sanskrit word udasin, i.e. one who is indifferent to or disregardful of worldly attachments, a stoic, or a mendicant. In Sikh tradition, the term iidasi has also been used for each of the four preaching tours of Guru Nanak ; in this sense, udasi meant a prolonged absence from home. Some scholars, including many Udasis, trace the origin of the sect back to the Puranic age, but, historically speaking, Sri Chand was the founder.
MUL CHAND, BHAI father in law of Guru Nanak, was a Chona Khatri, resident of Batala, who looked after the lands of the Randhava Jatts of the village of Pakkhokc in present day Gurdaspur district of the Punjab. He had a daughter of marriageable age named Sulakkhani whom he betrothed to (Guru) Nanak, then working as a modi or storeholder for the Nawab of Sultanpur Lodhi.
UDE SINGH (d. 1705), warrior and martyr, was the third of the sons of Bhai Mani Ram, a Parmar Rajput of `Alipur in Multan district (now in Pakistan). Ude Singh along with four of his other brothers received the rites of the Khalsa on the historic Baisakhi day, 30 March 1699. He was among the trusted 25 who constituted Guru Gobind Singh`s escort and took a leading part in battles fought in or around Anandpur after the creation of the Khalsa. Already in 1698 he had proved his skill as a musketeer when he killed a tiger during the chase.
