Not sure I understand. Are you saying it's sometimes necessary for you to forgive yourself, but it's never necessary for you to forgive someone else?
What I said: Yet, I still see in myself ways in which forgiveness is necessary for me.
What I also said: In reality, no one needs forgiveness.
The two aren't contradictory. Perception is a filter or veil pulled over reality. That reality is foremost about Self. And things aren't always as they seem. The reason I see forgiveness is necessary is because I perceive Self as split, separate from Self. Or perceive others as not Me. Seeing (reality of) everyone as Me, and knowing Love is complete/perfect within this Self, would render forgiveness as not necessary. Thus in reality, it is not necessary. Because I am willing to forego all that and hold conviction in an (alleged) existence of separation from Self, perceiving others, believing Love is between incomplete and not readily found, then it seems forgiveness is necessary. Emphasis on 'seems.' It is really just a desire, or offering to re-align what in reality is not out of accord, but due to my perception of reality/Self, is held in disaccord.
I do not see the two as honestly contradictory, but realize it may appear that way. From the perspective of 'forgiveness is not helpful,' and separation offers a lot more, the contradiction is a given. There is a duality at work (upholding the belief in separation) that cleverly masks itself with a broader, more superficial belief in plurality. Thus forgiveness appears to be about more (way more) than Me.
So do you mean it is unnecessary to overlook the the errors I perceive in others? That is, are you saying it is necessary to not overlook the errors of others?
My thought is there must be a typo in either premise (A) or premise (B) since they lead to what seems to me the opposite of the conclusion I think you trying to make.
It is not necessary for you to overlook the errors perceived in others. As in it is not a requirement from outside of you, placed upon you as if it is a burden, and salvation rests on you intellectually grasping this. In reality, you are, I am, we all are fine/perfect. If perfection currently strikes you as too high of a bar for you to see that in anyone, much less yourself, and you desire to see that, then forgiveness is the path to re-alignment. From the spiritual perspective, and answering the question of "why I am I here," then I see forgiveness as the only sane function. I hesitate to say that, due to my own desire to engage in other functions (namely to engage in what I perceive as enjoyment within the separation). Thus, if I say "forgiveness is your/my only function," I do get what this means, but also realize I am hypocritical in relation to that, for it is not the only function I engage in.
Wrapping one's head around what forgiveness is, as I said before, a lifelong process. I find it is really really obvious and very very simple to grasp intellectually. Seemingly too easy to understand. To apply, and apply consistently in all situations, is where the challenge comes. And seemingly never stops and also seemingly gets harder and harder.
Because of how simple it is to convey in words, and because I do recognize it as unnecessary in reality, I have high conviction that perfect knowledge of what forgiveness is, is known to all. To whatever degree that is presented as 'not true' to me, say by you claiming, "no really, I have no idea, please help me," is an intellectual exercise that may or may not show up as fruitful to me. I may never realize (intellectually) that you do understand. I do believe everyone practices actual forgiveness at least some of the time. As in, do you constantly focus on the errors of say Hitler and not allow yourself to live your life knowing the alleged horrors attributed to his persona? Or do you find yourself able to enjoy life, in your own way, by overlooking Hitler's errors, not to mention literally all errors by everyone, including own self, at least some of the time? Knowing you are able to find joy at any moment, and make that last, is partially how forgiveness is at work, and certain in its inevitable outcome (thus not really necessary). But understanding that today may be a day where you feel so at odds with another that death to them, or death to own self, suddenly seems rational, is the day where forgiveness suddenly becomes the most sane defense and 'necessary' for proper alignment of your Self.
I had to.
