The Universal Law of Wisdom, wisdom erases Karma
If you have the wisdom to learn your lessons through love and wisdom you can mitigate your suffering. Sadly, we seem to learn the fastest through pain, through directly experiencing the consequences of our actions. As an example, you greedily take from others, and instead of learning through wisdom and love that this is wrong, you have to experience from others someone greedily taking from you, whether later in this life or in a future lifetime.
Example: In your last life you were married to a Soul who is your mate today, and whom you cruelly left far another in that previous lifetime. Before you were born into your current life, you agreed to be left by your mate, under similar circumstances this will allow you to balance your Karma and directly experience the pain of abandonment. If through the wisdom of Master-Life-Awareness it is easier to detach consciously from the relationship with love, you will ease the pain of parting while also passing your own test, and thus absolving Karma and evolving from within.
A progression from the greedy, grasping toddler-like phase of me, me, me, we may evolve through being driven by ego-based desires and develop into a more centred, loving, giving, kinder adult. One of the ways we learn this is to experience what we don't want. By watching and learning from the behaviour of other people, from experiencing negative behaviour in others we also learn to appreciate the more harmonious qualities, giving us the choice to emulate the same, improved, more 'pleasing to be around' behaviour, or we can turn our backs on self-awareness and continue the path belonging to me, me, me. I guess this is wisdom. Attempting to deal with the challenges of life through a loving heart and mindset. Discarding the grey thinking, bringing pinkness and brightly coloured feelings of positivity and light.
