Ranas wanted to be different and respected. They copied a lot of things from Indian -muslm nababs. Darshan, aayesoyos, gayesoyos, not showing back etc etc is all copied form nababs from India , by Ranas. Sahas later copied that, and it slowly spreaded in the ktm valley. Back in those days, ranas were very scared of their power being taken away. They were specially scared by basnyats, thapas, and other regular chhetries. They stated a system called " chakadi" where regular ppl would have to visit these ranas in their house like almost everyday to show their obidence. In the time of Prithivi narayan shah there was no soyos. There was gaya , bhaya... etc.. like , " chetana bhaya". ... ranas stated this gayasoyos , aayesosos crap and it was for dominating purpose. for fake ego trip. No one with reasonable brain in a democratic society should stoop so low to make other person feel better. Tapai is enough. I am a cheetry myself, and i have given up saying this bullshit a long time ago.. I urge everyone to do the same. This aayeso - gaayeesooo thing was started on bad purpose, to dominate regular people , and since we have freedom and equal opportunity we should stop this fake ego boosting methods of talking.
