The doctrine of karma is a central theme in Tibetan Buddhism. It is related to the law of cause and effect. Based on this law, the doctrine of karma says that our present actions produce consequences. The consequences may be immediate or may appear years from now or even in another form of life. Karma is viewed as an effect rather than a cause, and karma is usually stored in the consciousness of a being.
Every person needs to resolve the effects of karma. You need to rise above the cycle of birth, death, and rebirth (samsara). Anyone can resolve it by directly addressing its cause. Tibetan Buddhism holds that by understanding the Four Noble Truths and living the Noble Eightfold Path, one can resolve karma.
