good post! i don't think enough people have *ever* considered this--that one harms oneself instantly and for "always", so long as, and while one's believing that self and others are separate. naturally, all that is an illusion...
It's so obvious! Yet, the simple is the opposite - always, of what the world teaches.
I find ho-oponopono to be wondrously healing, as well. And the blessings are equally for self and any perceived other. People miss so much grace and goodness, it's really heart-breaking, holding onto blame or any unresolved pains or ideas of same.
Another thing people don't think of is self-forgiveness. Often there's forgiveness of all others, and a real wish to be in union, and yet, the self-recrimination is sent deeper, and is that much harder to find.
