Sannyasa in the context of "Yogi"

The Vedas (/ˈveɪdəz/ or /ˈviːdəz/; Sanskrit: वेदः, romanized: Vēdaḥ, lit. 'knowledge'), sometimes collectively called the Veda, are a large body of religious texts originating in ancient India. Composed in Vedic Sanskrit, the texts constitute the oldest layer of Sanskrit literature and the oldest scriptures of Hinduism.

There are four Vedas: the Rigveda, the Yajurveda, the Samaveda and the Atharvaveda. Each Veda has four subdivisions – the Samhitas (mantras and benedictions), the Brahmanas (commentaries on and explanation of rituals, ceremonies and sacrifices – Yajñas), the Aranyakas (text on rituals, ceremonies, sacrifices and symbolic-sacrifices), and the Upanishads (texts discussing meditation, philosophy and spiritual knowledge). Some scholars add a fifth category – the Upāsanās (worship). The texts of the Upanishads discuss ideas akin to the heterodox śramana traditions. The Samhitas and Brahmanas describe daily rituals and are generally meant for the Brahmacharya and Gr̥hastha stages of the Chaturashrama system, while the Aranyakas and Upanishads are meant for the Vānaprastha and Sannyasa stages, respectively.

Yoga (UK: /ˈjəʊɡə/, US: /ˈjoʊɡə/; Sanskrit: योग 'yoga' [joːɡɐ] ; lit. 'yoke' or 'union') is a group of physical, mental, and spiritual practices or disciplines that originated with its own philosophy in ancient India, aimed at controlling body and mind to attain various soteriological goals (moksha), as practiced in the Hindu, Jain, Sikh, and Buddhist traditions.

Yoga may have pre-Vedic origins, but is first attested in the early first millennium BCE. It developed as various traditions in the eastern Ganges basin drew from a common body of practices, including Vedic elements. Yoga-like practices are mentioned in the Rigveda and a number of early Upanishads, but systematic yoga concepts emerge during the fifth and sixth centuries BCE in ancient India's ascetic and Śramaṇa movements, including Jainism and Buddhism. The Yoga Sutras of Patanjali, the classical text on Hindu yoga, samkhya-based but influenced by Buddhism, dates to the early centuries of the Common Era. Hatha yoga texts began to emerge between the ninth and 11th centuries, originating in tantra.

Gṛhastha (Sanskrit: गृहस्थ) literally means "being in and occupied with home, family" or "householder". It refers to the second phase of an individual's life in the four age-based stages of the Hindu asrama system. It follows celibacy (bachelor student) life stage, and embodies a married life, with the duties of maintaining a home, raising a family, educating one's children, and leading a family-centred and a dharmic social life.

This stage of Asrama is conceptually followed by Vānaprastha (forest dweller, retired) and Sannyasa (renunciation). Combined with other three life stages, Hindu philosophy considers these stages as a facet of Dharma concept, something essential to completing the full development of a human being and fulfilling all the needs of the individual and society.

Āśrama (Sanskrit: आश्रम) is a system of stages of life discussed in Hindu texts of the ancient and medieval eras. The four asramas are: Brahmacharya (student), Gṛhastha (householder), Vanaprastha (forest walker/forest dweller), and Sannyasa (renunciate).

The Asrama system is one facet of the Dharma concept in Hinduism. It is also a component of the ethical theories in Indian philosophy, where it is combined with four proper goals of human life (Purushartha), for fulfilment, happiness and spiritual liberation. Moreover, since the four asramas can be seen as the framework of an influential life-span model, they are also part of an indigenous developmental psychology which from its ancient beginnings until today has shaped the orientations and goals of many people, especially in India.

Vānaprastha (Sanskrit: वानप्रस्थ) literally meaning 'way of the forest' or 'forest road', is the third stage in the 'Chaturasrama' system of Hinduism. It represents the third of the four ashramas (stages) of human life, the other three being Brahmacharya (bachelor student, 1st stage), Grihastha (married householder, 2nd stage) and Sannyasa (renunciation ascetic, 4th stage).

Vānaprastha is part of the Vedic ashrama system, which starts when a person hands over household responsibilities to the next generation, takes an advisory role, and gradually withdraws from the world. This stage typically follows Grihastha (householder), but a man or woman may choose to skip householder stage, and enter Vānaprastha directly after Brahmacharya (student) stage, as a prelude to Sannyasa (ascetic) and spiritual pursuits.
