The word "udasi" is derived from the Sanskrit word "Udasin", meaning "detached, journey", reflecting an approach to spiritual and temporal life, or from "udas" ("detachment"), signifying indifference to or renunciation of worldly concerns. The sect is based on the teachings of Guru Nanak's elder son Sri Chand (1494–1643), who, contrary to his father's emphasis on participation in society, propagated ascetic renunciation and celibacy. Another Sikh tradition links the Udasis to Baba Gurditta, the eldest son of Guru Hargobind, and there is dispute on whether the Udasis originated with Sri Chand or Gurditta.
