A bucket, a couple of towels, a couple of old pillows, a punching bag, a secluded, relatively soundproof place, a bottle of water.
Breathe, grunt, cough, spit, punch, scream, vomit, - let go.
Breath - let the breath be free, deep, hot, shallow, hard. Don't try to control it.
Don't fix on any thought. Let them tumble freely.
Change your relationship to your anger. Instead of saying, thinking - 'I am angry' say think 'there is at this moment a sensation that iscalled anger, it comes and goes. Sometimes intense, sometimes it disappears.
Anger is a fire emotion with hot sensations. Hot skin, hot breath, hot thoughts.
Instead of saying there is anger, say there is heat.
Slowly, over time, the heat cools. The fire goes out. The anger is gone.
To cool something hot, put something cool on it.
Don't put petrol on a fire. Put water on it.
Friendliness, forgiveness, caring is water to anger.
Develop caring, first for yourself, then everybody, thing, else.
Care, and let go...
