How people treat you is their karma; how you react is yours.
Acceptance means no complaining, and happiness means no complaining about the things over which you can do nothing.
Remember, purpose is about giving...All you can do with your life is to give it away in the service of others.
Your teacher might be a child who takes you by the hand and asks you a question that you hadn't considered before, and your answer to the child is your answer to yourself.
You must become the producer, director and actor in the unfolding story of your life.
Not only do you become what you think about, but the world also becomes what you think about. Those who think that the world is a dark place are blind to the light that might illuminate their lives. Those who see the light of the world view the dark spots as merely potential light.
