Psychological viewsEarly theories Gautama Buddha discussed the role of the mind in the pursuit of happiness through the practice of the eightfold path. According to Buddha, "Mind is the forerunner of states of existence. Mind is chief, and (those states) are caused by the mind. If one speaks and acts with a pure mind, surely happiness will follow like one's own shadow!" In Buddhism, the third of the Four Noble Truths states "to eliminate suffering, eliminate craving", thus establishing happiness as beyond material and emotional possession and attainable only through an attentive practice leading to extinguishing of craving and aversion. According to Jainism, happiness and bliss is the natural state of the soul. A soul when liberated from all its karmas experiences infinite bliss, knowledge and perception.
