Almost all Sikhs know that nindiya is bad,very bad. But gurbani says that ustat is also bad.
Punjab is full of deraas. These dere vaalas do so much ustat of their "brahmgyani sant baba" that the people's head begins to bow for their sant baba.
Ustat is the main reason people get attached to deraas instead of Guru Sahib.
Sikhs shud be watchful against this ustat tactic of dere vaalas.
