the active pursuit of Kama and Artha on the other. This has led to the concepts of Pravrtti (प्रवृत्ति, Pravritti) and Nivrtti (निवृत्ति, Nivritti), with the former meaning "giving or devoting one's self to" external action, while the latter means "withdrawing and restraining one's self from" external action in order to focus on one's own liberation. Artha and Kama are Pravrtti, while Moksha is Nivrtti. Both are considered important in Hinduism. Manusmriti, for example, describes it as, Indian scholars offered a creative resolution to the tension between "action"-filled life and "renunciation"-driven life, by suggesting the best of both worlds can be achieved by dedicating oneself to "action with renunciation", that is when "action is without attachment or craving for results". Action must be engaged in because it is Dharma, that is, it is good, virtuous, right, a duty and a moral activity, and not because of one's craving for the results or material rewards without any consideration for Dharma. This idea of "craving-free, dharma-driven action" has been called Nishkama Karma in Bhagavad Gita. Other Indian texts state the same answer to tension between "pursue wealth and love" versus "renounce everything" Purusharthas, but using different words. Isa Upanishad, for example, states "act and enjoy with renunciation, do not covet". Origins of puruṣārtha theory The concept of mokṣa appears in the Upanishads, while the preceding Samhitas, Brahmanas and Aranyakas commonly refer to kāma, artha and dharma as the "trivarga" or "three categories" of possible human pursuits. The Dharmaśāstras and the epics Ramayana and Mahabharata are the first known sources that comprehensively present the notion that integrated living entails the pursuit of four goals or ends. Prasad (2008) states that the division between the trivarga and mokṣa is intended to highlight the context between the social (trivarga) and personal (mokṣa) spheres. The Sannyasa is entirely focussed on the pursuit of Moksha without violating Dharma. Baudhayana Dharmasūtra, completed by about 7th century BC, states the following behavioral vows for a person in Sannyasa, Baudhāyana also makes repeated references to the Sannyasa (ascetic) stage and its behavioral focus, such as in verses II.13.7 and 11.18.13. This reference, Olivelle states, is found in many early to mid 1st millennium BC texts, and is clearly from gnomic poetry about an established ascetic tradition by the time Baudhayana Dharmasutra and other texts were written. Katha Upanishad, in hymns 2.1–2.2 contrasts the human feeling of pleasant (preyas, प्रेयस्) with
