Am curious, about a Sakhi I heard a few times at Gurdwara/ radios. When Guru Amar Das Ji went to visit Guru Angad Dev Ji for the first time, Baba Amar Ji thought "I will consider Guru Angad a true Guru if he knows am a vegetarian."
In langar they sat close to each other and the second Guru said, to the sevadar serving food "Bhai Ji. Serve Baba Amar Das vegetarian items only," then Baba Amar Das was convinced this IS the real deal, the true Guru Sahib.
QUESTION!!! Doesn't this mean meat was being served in langar up to Guru Angad Dev Ji's Guruship?
