buddha taught a middle way between expression and suppression. observe the anger as it were a meditation object. the anger is not yours. just be aware of the anger simply note it with a mental note, say in your head, anger, anger, this is anger. this alone, this awareness of the anger, is a wholesome state, because your not saying I AM angry your saying here is this anger. your not identifying with it. this will keep you from bottling it all up, or expressing it through violence or words. also important to remember the situation or person in ultamite reality does not have a self. who are you mad at???? what are you mad at? its gone. EVERYTHING IS IMPERMANENT. how can you be mad at it. hahahahahh. hahaha take care, Befriend. check out mindfulness of concisousness the third of the four foundations of mindfulness.
nothing can destroy a man who has lived a pure life
