Among all of the retributions for committing bad acts, the retribution for hatred is the greatest. The other fetters do not have such severe punishments. When one slays hatred the mind will have no regrets.
Hatred is the root of poisonousness.
Hatred destroys every form of good. When one slays hatred, all buddhas offer praise. If one slays hatred one has no more distress. I wish to cause beings to gain happiness. Hatred devours and destroys all forms of goodness.
