The lamrim clearly states that one moment of anger destroys eons of merits.
Thus some further questions arise:
1. what actually is anger?
I'll try this: strong dis-liking arising out of a state of suffering and ignorantly projecting an "exterior object" as the cause for the experienced suffering, this "object" become the object of our anger and we strongly believe our anger (and the resulting actions) to be entirely justified.
So anger is first a THOUGHT.
From this tought, various mindset can develop and we can easily engage into regrettable actions.
Examples: anger as jealousy, anger as depression, anger as fear, anger as paranoia, anger as ressentment...
And examples of actions: lying, rough/hurtful speech, dividing speech, lies, thefts, sabotage, putting other down, murder!
Where is the ignorance in this process? The ignorance is the wrong identification of an "external object" as the cause for our state of suffering.
This means that we are HURTING the object of our anger thinking that we can solve our suffering, but we are "attacking" the wrong object, and in doing so we eventually make ouir potentialities for anger more likely.
Acting out of anger may seem as if we are solving a problem, but it isn't.
We can easily think of examples of that in our lives, when we have acted out of jealousy or hatred (well, I can).
ANGER is at the opposite end from a mind of enlightenment.
ANGER is a pitfall to darkness, the darkness of EGO, it is a counter-productive "self"-defense reaction, pityfull and plain stupid.
Anyone wants to add to this?
2. is it only anger that destroys merits, or is it also desire, pride, ignorance, doubt...?
Can someone cast light on this?
3. since we are not enlighetened yet (well, me at least), how can we make sur we dedicate properly? uuuhhh...
Hehe, I found the answer to that in the lamrim, and it s so simple, it blew me away...
At the end of our dedication, we dedicate just like the buddhas dedicated, or just like our teacher dedicates.
