Self-mastery entails self-discipline, but neither self-mastery nor self-discipline is a matter of applying superior force. It is not like a parent pushing a child to do her homework long enough that she finally grudgingly does it to avoid being scolded by her parents. Self-discipline can be developed joyfully rather than as a burden we impose on ourselves. It can become something we willingly embrace. This requires training – mind training. We need to recognize that our minds are big enough and can open wide enough to accept reality. We need to talk to our minds. The aim is for us to choose, wholeheartedly, to do what we know is the best thing to do. Self-discipline ~ 17th Karmapa
