my own $0.02,

forgiveness can vary from point to point in time, as Granite said (no that's not nutty, Granite, that's human nature. We vacillate.... It's part of the territory.)

"feeling it and knowing that it's true" is pairing up two things that don't necessarily have to go together. You can truly, really, love someone, without feeling hearts & flowers at every moment. So if you decide to forgive, while in yr "wise mind", and later yr feeling surprise you, well, I wouldn't stress over it. You may have more to work through, but your resolve is still steady.

I think that wanting to be a forgiving person, toward others, is what's asked. But where self forgiveness comes into it, and why the T community generally points people toward that, is still a puzzle for me.
