Are Radha soamis, Narakdharie and all these other dera followers sikhs? No. A thread:

First: What defines a Sikh?
- Believes in one, omnipresent God
-Believes in ALL ten gurus and their teachings
-Accept sri guru granth sahib ji as your ONLY living guru
-Believe in the writings of ALL ten gurus
-Cannot have another religion or any guru
-Must follow Gurus Hukam

So why aren’t Radha Swoamis Sikhs?
-Waheguru gurmantra is not accepted
-They recite kachi bani(bani from other people) mixed with gurbani( disrespect to guru granth sahib maharaj)
-No Panj pyare
-Allowed to consume tobacco( strictly forbidden in sikhi)

-believe in a living Guru( they call him satguru). This goes, as mentioned above, against sikhi
-Don’t believe in the philosophy of Khalsa
-They whisper a secret name into their followers names, which they then have to recite. This is manmat and not gurmat.

An quote from the book mera satgur written by radha swoamis says: "Only alive human can be the true guru. No one from previous times can be our guru. (Page 59-60)"

Sawan , a radha swoami, in his book Gurmat Sidhant: “Granth cannot show us the true path” (Page 66)

Guru Gobind singh ji maharaajs hukam is: Agea pai akaal ki, tabhe chaleo panth sab sikhan ko hukam hai, guru maneo granth. Guru granth ji maneo pargat guran ki deh.

Narkdharie, Radha swoamis and dera followers, have mocked sikh gurus a lot in the past and still are. There are many pictures you can search online

Anyone who prays to and follows other living humans and calls them gurus and doesn’t follow Guru granth sahib ji maharaaj as their only guru, is not a sikh. Bhul chuk maaf
