In ancient times, Parishad was the assembly of learned scholars called by the king to decide on the subjects of Vedas, Vedanga, Dharmashastra, religion etc.
[6] According to Parâsara four, or even three learned Brahmins in a village, who know the Vedas and keep the sacrificial fire, form a Parishad.
[7][8] There are references of Pariṣad in Chhandogya and Brihadaranyaka Upanishads where discussion of metaphysical subjects of Atman and Brahman were organised.
According to Kautilya, Tantra-Yukti was compiled by systematic debates in the Parishad of learned Brahmins possibly in the 6th century BC.
[9] Kashi, Mithila, Kosala, Kuru, Panchal, Pravahana Jaivali's palace, Kekaya Aswapthi's sabha, Mahasala of Sounaka, Yajnavalkya Ashram in North India, PathanjalaKapya's gurukula, Bhrighu's and Dathathreya's schools in South India were some important centres of the Vedic Parishad.
