Namdhari
Naamdharis believe in the continuation of the Guru lineage in human form after Guru Gobind Singh ji left his mortal body in 1708. This sect was founded by Bhai Ram Singh of Bhaini. They are not accepted as Sikhs by the main Sikh population. However, The Namdhari consider themselves as Sikhs. They are also known as Kookas' or Kukas. The men are distinguished as they wear white, "round" turbans with the ears fully exposed. The more orthodox Kukas also wear wear attire which included very tight pants and long kurtas.
Apart from the belief of more than ten Gurus, they also have many non-Sikh traditions like worshipping of fire (havan), which is more akin to Hinduism than Sikhism. They do not believe in Khanda di Pahul and the Vaisakhi of 1699.
