i may add that Guru Nanak Dev Ji had the courage to challenge the bigotry, ritualism , unequality , and the practitioners to these ghastardly
acys right at their doorsteps, not fearing the concequences, thus setting before us example to practice what he called in his 9th incarnation
, Sri Guru Tegbahadur Sahib ji - bhai kahu ko det nahi, nah bhai manat aan kaho Nanak sun rei mana giani tahe bakhaan ( that person, who
does not terrorise others, nor can he be terrorised by any one , O Nanak he (such man )only is to be described as Gyani(the learned One)
he neither feared the political class nor the religious one, and pointed out in fearless manner their shortcomings and mistakes
May god lead us to follow example set before us by such great GURUs
