Joy kaomoji describes the pervasive mental conditions that humans and other animals experience as positive, enjoyable, and discoverable mental states. It also includes specific mental states like happiness, entertainment, happiness, ecstasy
and euphoria. In psychology, under the Ananda principle, ananda is described as a positive reinstatement mechanism that encourages the organism to make precisely the situation within the future that he or she has just experienced.
In line with this theory, organisms are thus encouraged to not repeat situations that have caused them some reasonably anguish within the past. The experience of bliss is subjective and every person experiences pleasures of various types
and quantities within the same situation. Many blissful experiences are related to fulfillment of basic biological functions such as: food, exercise, work and even toilet.
Other joyful experiences are related to social experiences and social activities, like achievement, recognition and repair. The appreciation of cultural artifacts and art, music and literature are often delightful. Narcotic use can even
provides a pleasant feeling: Some drugs, illegal and otherwise, cause euphoria within the brain when ingested. In step with the natural tendency of the mind (as described within the theory of pleasure), such a sense only results in
subordination and addiction.
