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. The Udasis are a type of Sehajdhari or Sanatan Sikh, rather than orthodox Khalsa Sikhs.
