I read your letter and was very, very happy that you did the Vajrasattva retreat.

Regarding your question about sur practice, it was Geshe Lama Konchog who said that once we start sur then we need to continue.

Geshe Lama Konchog used the example that if we give food to a beggar, then the next day the beggar would expect it again. Once we gave food to them, they would expect it every day. It is logical reasoning. So, you can figure it out from there.

But some people do sur just for 49 days after someone passes, and after 49 days they stop.

Anyway, you can do it as much as possible. Even if you can’t promise to do it every day, please do it as much as you can.
