Nātya Śāstra was created by Supreme Brahman from the Vedas. The recitative texts are from Rg Veda, the musical songs from Sāma Veda, abhinaya from the Yajur Veda and rasa from Atharva Veda. Thus Nātya Śāstra has been brilliantly carved out of the four Vedas embedded with the hidden meanings of the Vedic Scriptures and the Vedāṇgas and is hailed as the fifth Veda.
