In Buddhism, one of the “Three Universal Truths” is the law of Karma.
The law of Karma says that for every event that occurs, there will follow another event which was caused by and is a reaction to the first. The second event will be pleasant or unpleasant according to the intention of the first event. In other words, if the first event is of good nature, the second event will be as well. However, if the first event is of ill nature, the second event will be too.
Therefore, the law of Karma teaches us that the results of our actions and their reactions are the responsibility of the person who commits them.
“My actions are my only true belongings.”
