I concur with the thoughtful and consequential writing. And, I  have similarly realized that resentments/grudges actually do me more harm than the persons the energy is beholden against, for their actions. It is a power that I’d rather try to not give others. Their living rent free in my psyche is detrimental to my peace and meditation.

I don’t necessarily forget, because something can be learned from the experiences. As for forgiveness, I happen to think of that more just as a lip service to would be transgressors, that can help them release the negative energies. So it is a graceful act, in my opinion, that I am normally comfortable giving.

Although, one may get upset or even angered by others' actions, whenever possible, it is best to relieve the yogi’s psyche, by settling situations as much as and as soon as possible, and as much as necessary. That unburdening will be felt, so your conclusions and decisions, IMHO are astute.

And, in the case of interactions with individuals who are no longer available for one to communicate with in typical ways, then dispensing in the form of thoughts can be undertaken, all in the aim of protecting meditation.
