Anger is something you should only vent in front of intimates, and friends and relations. Never be angry in front of strangers because you lose face.
James ClavellTo think bad thoughts is really the easiest thing in the world. If you leave your mind to itself it will spiral down into ever increasing unhappiness. To think good thoughts, however, requires effort. This is one of the things that discipline and training is all about.
James ClavellKarma is the beginning of knowledge. Next is patience. Patience is very important. The strong are the patient ones, Anjin-san. patience means holding back your inclination to the seven emotions: hate, adoration, joy, anxiety, anger, grief, fear. If you don't give way to the seven, you're patient, then you'll soon understand all manner of things and be in harmony with Eternity.
