Bro this fool redoptics look so fake first of all
its guru Nanak dev ji learn how to respect guru sAhibaan second you don’t even know what gurmat is
how u know he was Avtar of Vishnu??
All these Demi gods rejected by guru Nanak dev ji start studying Gurbani if he was Avtar of Vishnu why would Gurbani say
ਗੁਰਨਾਨਕਦੇਵਗੋਵਿੰਦਰੂਪ॥੮॥੧॥
Guru Nanak is embodiment of the Light of God. (Ang 1192)
