All too often, old karma manifests itself in feelings of guilt and inadequacy. Essentially, we are all innocent, and everything is forgiven as each moment clears away the past without a trace of karma. However in order to become a witness to our innocence, we must be in a space in which we are not holding onto grudges. Thus, we can create a shift in perspective and see our true nature ever more clearly. For this reason, the question might be better posed, "How can I heal my own misperceptions?"
In my experience, an effective approach begins with the acknowledgement, "If I knew better, I would do better." This statement is only constructive if we are truly prepared to do better. Otherwise, it is simply an avoidance tactic that temporarily frees us from fully owning our responsibility to initiate the healing process. To be an able participant in healing the past, we must be willing to remain open and to allow love to speak for us.
Sadly, so very few of us have been conditioned to trust in love to do its work. In fact, most of us realize through the indifferent reaction we get from others that our love alone is not quite good enough. Besides, the path of openness and love never serves the ego, which is why we so often reject the obvious solution. Something extra is wanted, and in the throes of wanting, the apparent healing capacity of love is all too easily overlooked.
And still, this is my soul response, "Offer love and recognize that love is the ultimate healer regardless of how it is, or is not, received."
