There are two ways that we respond to hurt and resentment that we experience in our material life. We either learn not to behave in a way that causes hurt to others as we know how it feels or we become bitter and do unto others the pain we experience, in exactly or worse way after careful panning and manipulation.
The former lightens our own energy field and is a step toward spiritual maturity and emotional intelligence, and that latter builds more and more layers of negativity and ignorance. The choice is always ours!
