According to the law of karma, it depends on you. Your karma, your world, how you experience life depends on you. On one side is the groundless, the emptiness. The other side is karma, very meticulously calibrated causes and effects. You reap what you sow.
Positive things get positive results, and negative things get negative results.
You get to choose. It is all in one's own hands. One is responsible for oneself and for the world. It's all connected. You are responsible for your patch, which is part of the big patch.
