My dear brāhmaṇas, I have now explained to you the confidential knowledge of Sāṅkhya, by which one philosophically distinguishes matter from spirit, and of aṣṭāṅga-yoga, by which one links up with the Supreme. Please understand that I am the Supreme Personality of Godhead, Viṣṇu, and that I have appeared before you desiring to explain your actual religious duties.
