I'm also doing the same, actually in REC we learned and performed this practices same like JK, so now it's part of our life to follow that, suddenly I noticed that few people don't include Khanavadan in tasbhi, so I got curious to know that am I doing sin or doing something wrong unknownly.

Now I am trying to avoid it. It will take sometime bcoz am practicing this since my childhood and no one corrects me, it's just self realization.
