Best understood as aesthetics, the definition of Kama involves sensual gratification, sexual fulfillment, pleasure of the senses, love, and the ordinary enjoyments of life regarded as one of the four ends of man (purusharthas).
Kāma (Sanskrit, Pali) means desire, wish, longing in Indian literature. Kāma often connotes sexual desire and longing in contemporary literature, but the concept more broadly refers to any desire, wish, passion, longing, pleasure of the senses, the aesthetic enjoyment of life, affection, or love, with or without sexual connotations.
Kāma is one of the four goals of human life in Hindu traditions. It is considered an essential and healthy goal of human life when pursued without sacrificing the other three goals: Dharma (virtuous, proper, moral life), Artha (material prosperity, income security, means of life) and Moksha (liberation, release, self-actualization). Together, these four aims of life are called Puruṣārtha.
