There are four laws of karma as follows:
1. Results are similar to the cause. Karma and its results are certain and unfailing. Positive actions of body, speech, and mind will always bring the positive result of some form of happiness and benefit. Negative actions of body, speech, and mind will always bring the negative result of some form of suffering. Karma and its results are exactly like a seed and its fruit.
2. No results come without a cause. Actions not engaged, will not bring results. It is obvious that things do not just appear out of nothing. If the cause has not been created, the effect will not be experienced.
3. Once an action is done, the result is never lost. An action done, is not lost and will definitely ripen and bring a result.
4. Karma expands. Once we have an imprint of an action in our mind, it tends to be habit-forming.
