Forgiveness holds itself to provide the external party an opportunity to aide another in their transgression toward them. To forgive is to realise the scope of the circumstance and to decide just how long such feelings are to be stirred until they are let go. One could say that forgiveness is a gratitude to the person, self, and context, that in forgiveness we find our own solace and accept how we feel, we find gratitude for the other party, and the entirety that led to the context in the first place. Forgiveness serves as an expression too, and as such aides in the bonding of many and the tightening of relationships. Baggage is an almost certainty, it is the ability to support, forgive, and work through each case with and when another provides such the chance.
Meditate.
