The Vanaprastha stage ultimately transitioned into Sannyasa, a stage of complete renunciation and dedication to spiritual questions. Vanaprastha, according to Vedic ashram system, lasted between the ages of 50 and 74. Nugteren states that "Vanaprastha" was, in practice, a metaphor and guideline. It encouraged gradual transition of social responsibility, economic roles, personal focus towards spirituality, from being center of the action to a more advisory peripheral role, without actually requiring someone to actually moving into a forest with or without one's partner. While some literally gave up their property and possessions to move into distant lands, most stayed with their families and communities but assumed a transitioning role and gracefully accept an evolving role with age. Dhavamony identifies Vanaprastha stage as one of "detachment and increasing seclusion" but usually serving as a counselor, peace-maker, judge, teacher to young and advisor to the middle-aged. Hindu traditions respected freedom and personal choice. While "Grihastha" and "Vanaprastha" stages of life were recommended, they were not a requirement. Any "Brahmacharya" may, if he or she wants, skip householder and retirement stage, go straight to Sannyasa stage of life, thereby renouncing worldly and materialistic pursuits and dedicating their lives to spiritual pursuits. Jamison and Witzel state early Vedic texts make no mention of life in retirement, or "Vanaprastha", or "Ashrama system", unlike the concepts of Brahmacharin and Grihasthi which can be distinguished. The earliest mention of a related concept in Rig Veda is of "Antigriha" (अन्तिगृह, like a neighbor) in hymn 10.95.4, where the context and content suggests the elders did not go into forest, but continued to live as part of extended family, with outwardly role, in ancient India. In later Vedic era and over time, "Vanaprastha" and other new concepts emerged, while older ideas evolved and expanded. The concept of "Vanaprastha", and Sannyasa, emerged about or after 7th Century BC, when sages such as Yājñavalkya left their homes and roamed around as spiritual recluses and pursued their "Pravrajika" (homeless) lifestyle. The Dharmasūtras and Dharmaśāstras, composed about mid 1st millennium BC and later, place increasing emphasis on all four stages of "Ashrama system", including "Vanaprastha".
