Karma

Karma (las): A Sanskrit word meaning "action", which refer to the law of cause an effect related to our thoughts, words and behavior. According to the Buddha's teachings, beings' destinies, joys, sufferings, and perceptions of the universe are due neither to chance nor to the will of some all-powerful entity. They are the result of previous actions. In the same way, beings' future are determined by the positive or negative quality of their current actions. Distinction is made between collective karma, which defines our general perception of the world, and individual karma, which determines our personal experiences. [MR]
