A lesson from Master Patana:
The anger in you reflects a revengeful mind, it is the unconscious egoistic mind that seeks revenge. Whenever you are angry, be all aware and watchful of how the revengeful mind arises.
A revengeful mind can only arise out of anger. It hurts others; it punishes others; it curses others, blames others, it speaks ill of others, and could even escalate to the idea of murder. It is the unconscious ego at work. Be watchful of this mind, the rebellious mind that arises out of ego.
It is the animalistic and reptilian mind.
It reflects the inferiority. It reflects cowardice.
To protect its own well-being, the ego protects itself by crippling others. Because it is inferior within itself, there are no other ways to feel better than to cripple others or to speak ill of others to feel superior again.
Stay aware of the ugliness of such minds as it arises, there is nothing more to do than to be all mindful and watchful. And start realizing the stupidity of allowing the ego possess and take over your thoughts and actions.
