The Rigveda mentions the word Dhruva (meaning both "pole star" and "fixed") dozens of times, and the pole star has not been explicitly mentioned anywhere at all in the Vedas. Grihya-Sutra, Mahābhārata, Surya Siddhanta, etc., however, mention Dhruva as the pole star. Pāṇini mentions Dhruva as "a fixed point from which departure takes place".
