What does "The Road to Hell is Paved with Good Intentions" mean?

[zedro]

I think it comes from our ability to forgive ourselves. For example, if our intent was to do harm and we do it, we may find it harder to forgive ourselves. But if you do harm without having the intent, then you may find it much easier to bring yourself to forgive yourself.

That is one aspect/tool, but not everything requires forgiveness, unless you think it does. We are trying to meet our evolutionary potential, and karma is the expression of that motivating force. So I would say a more generalized view is 'learning', forgiveness can be nested inside that. However the paradigm for 3rd density karma appears to be more specifically centered around forgiveness/acceptance, at higher densities the focus would be different.
