try to cure the pain by converting it to joy and happiness.

I have seen people doing that. They were into body modification and BDSM and for every pain inflicted they would feel the adrenaline rush and the pain would go away. and a time comes when they stop feeling the pain and it is all the adrenaline rush. Our body also has the ability to produce its own pain killers called endorphins.

is that whay you mean by converting the pain to joy and happiness?
