The earliest Jaina texts, on Dhyana such as "Sutrakranga", "Antakrta-Dasanga" and "Rsibhashita", mention Uddaka Ramaputta who is said to be the teacher of some meditation methods to Buddha, as well as the originator of "Vipassana" and "Preksha" meditation techniques. The Jaina tradition believes Rishabhanatha, the first Tirthankara, to have founded meditation, but there is no historical confirming evidence. The earliest mention of Dhyana in the canonical Jaina texts simply mention "Dhyana" as a means of emancipation, but in them ascetic practices are not emphasized nor is the discussion as systematic as in later Jaina texts or Hindu texts such as the Patanjali's Yogasutras. There is no archeological or literary evidence, states Sagarmal Jain, about the origins of systems for Dhyana and Yoga, and there is a great deal of similarity between Jaina, Buddhist, Ajivika, Samkhya, Yoga and other ancient Indian traditions. The earliest texts, such as "Tattvarthasutra" suggest that these ideas developed in parallel, sometimes with different terms for similar ideas in various Indian traditions, influencing each other.
