Q: Do the Adinathas still exist?

A: The Nathas is a living group and the Adinath tradition continues.
The following is a statement from Lokanath Maharaj.

"I was initiated into the Adinath Sampradaya at the spring equinox in 
1978 by HH Shri Gurudev Mahendranath (Dadaji), who bestowed on me the line 
of succession (parampara) of that group. His guru was HH Shri
Lokanath Maharaj of Uttara Kashi (Himachel Pradesh).

"Dadaji was keen that the wisdom of the Nathas should have wider exposure 
than just the subcontinent of India and when I returned to 
the UK from India I initiated several people as Adinathas.
