Have you ever thought to send love and light energy to someone you can not stand? You would think that if someone did you wrongly or should learn their lesson by what they have done to someone that you thought they cared about should feel bad and negetive.
If you think of this person in your deepest thoughts and send them love you are creating good Karma, good energy. If you think of someone with negetive thoughts you're creating negetive Karama. Have you ever heard of the saying, you will get what you put out there? It will bummerang on you and come back to you. What I am trying to say is to be positive. Take only positive energy inside you. If someone tries to pull you into their mucky energy, try to make you feel bad for something you're not too proud of either, don't take it. You're accepting their bad Karma.
Hold onto your love, kiss it into the palms of your hands. Hold onto it with love and through it back into the Universe.
