Brahmā said: The three mātrās and half a mātrā called nāda, together constitute Brahman. The three Vedas Ṛk, Yajus and Sāman are in the form of the three mātrās. Viṣṇu contemplated on Śiva, the universal soul, through the words of the Vedas. The Vedas became a sage. Viṣṇu understood the glorious essence of the Vedas—the supreme lord through that sage alone.
