(3) How can confession be an antidote to the 3 poisons?
Because the 3 poisons which are ignorant, hated and desire are the root cause of the non-virtuous actions but only confess about it then repeat again, definitely can't antidote the 3 poisons, so one must do the practice of four opponent powers as well so that we didn't repeat the non-virtuous again.
Come to think of it, someone who is convinced of the righteousness of a non-virtuous action would
never confess sincerely!
If in my mind I can justify the act of killing, or lying, or stealing, etc... then how could I possibly "confess"?
On the contrary, I could even go about tell others what I did it to get recognition for it and it would be my "trophy." - Delusion!
Example:
I have killed Hitler.
In my mind that killing was justified.
In my mind that killing is still justified.
Then why on earth would I confess this act? It is not logical.
So I understand "confession" to be an antidote to the 3 poisons like this:
3 poisons:
-ignorance
-desire
-hatred
We need to STOP justifying our non-virtuous act!
I have come to the realisation that my mind was blinded by desire, by hatred or by ignorance in justifying my action.
I realize that desire, hatred and ignorance are not foundations that can validate an action of killing, stealing, lying, etc...
Only then can I start a process leading to a confession.
So I think this is how a SINCERE confession is an antidote to the 3 poisons, for it makes wisdom win, for once, against ignorance (ignorance being the root of the other 2 poisons).
Confession is simply IMPOSSIBLE if we are not our self stepping onto the 3 poisons just like in the representations of Heruka or Vajrayogini.
