Cute Young Brunette Girl Practicing Yoga Poses

History
The Vedic Samhitas contain references to ascetics, while ascetic practices ("tapas") are referenced in the Brāhmaṇas (900 to 500 BCE), early commentaries on the Vedas. Several seals discovered at Indus Valley Civilization (c. 3300–1700 BCE) sites in Pakistan depict figures in positions resembling a common yoga or meditation pose, showing "a form of ritual discipline, suggesting a precursor of yoga," according to archaeologist Gregory Possehl. Some type of connection between the Indus Valley seals and later yoga and meditation practices is speculated upon by many scholars, though there is no conclusive evidence.
Techniques for experiencing higher states of consciousness in meditation were developed by the shramanic traditions and in the Upanishadic tradition.
While there is no clear evidence for meditation in pre-Buddhist early Brahminic texts, Wynne argues that formless meditation originated in the Brahminic tradition, based on strong parallels between Upanishadic cosmological statements and the meditative goals of the two teachers of the Buddha as recorded in the early Buddhist texts. He mentions less likely possibilities as well. Having argued that the cosmological statements in the Upanishads also reflect a contemplative tradition, he argues that the Nasadiya Sukta contains evidence for a contemplative tradition, even as early as the late Rg Vedic period.
