Question: Is annulment a skill?

Answer: Annulment is when you have no personal involvement in the future. You are like a slave who is obliged to do everything your master tells you. But at the same time, you do not expect any reward. You fulfill his desire not involuntarily, but consciously, of your own freewill.

Question: Is revealing the friend’s Hisaron my goal?

Answer: You cannot reveal his Hisaron and you never will. You strive with all your desire to help him. You do not reveal it for yourself, but wish to fully participate in it. In this, you are his slave.
