Udasi

Udasis (Gurmukhi: ਉਦਾਸੀ ਸੰਪਰਦਾ; udāsī saparadā) (Devanagari: उदासी संप्रदाय), also spelt as Udasins, also known as Nanak Putras (meaning "sons of Nanak"), are a religious sect of ascetic sadhus centred in northern India who follow a tradition known as Udasipanth. Becoming custodians of Sikh shrines in the 18th century, they were notable interpreters and spreaders of the Sikh philosophy during that time. However, their religious practices border on a syncretism of Sikhism and Hinduism, and they did not conform to the Khalsa standards as ordained by Guru Gobind Singh. When the Lahore Singh Sabha reformers, dominated by Tat Khalsa Sikhs, would hold them responsible for indulging in ritual practices antithetical to Sikhism, as well as personal vices and corruption, the Udasi mahants were expelled from the Sikh shrines.

The word Udasi is derived from the Sanskrit word , meaning 'detached, journey', reflecting an approach to spiritual and temporal life, or from ('detachment'), signifying indifference to or renunciation of worldly concerns.
