I just answered How to control anger according to sunnah?, and it struck me as likely that Sufis might have a different interpretation of anger and a different approach to coping with anger, perhaps more spiritual than other Muslims.
Googling sufi anger
gives two references:
Sufi University: He says that if you’re angry, then you do the Sufi practice of tawbah and return to divine love now. The tawbah practice can be used to bypass by the past and the 'root' of the problem.
Sufispirit.com.au: When a person gets angry, this is a form of pride. They are saying, 'I am better than you'.
So it seems likely that there's a different attitude in Sufism to anger. However, I don't know how reliable/accurate these references are among Sufis.
Question: What is the Sufi interpretation and method to control anger?
