'Sāṅkhya' denotes jñāna — the pure knowledge of the nature of the self (ātmatattva-vijñāna), as declared by the Lord and in the Smṛtis of Vyāsa. 'Yoga' is the means; 'yogāḥ' are the practices resorted to by people for liberation and welfare. Because the passage uses these terms in opposition, both sāṅkhya and yoga are here treated as applicable methods. Where both terms occur together elsewhere, they indicate method (upādēya) — for example in the Pañcarātra and Citraśikhāṇḍa schools which derive from Vedic roots and sometimes use 'sāṅkhya-yoga' collectively. 'Yuktēś ca jñānam' — 'jñāna' preceded by 'yukta' means knowledge joined with means. 'Upāyaś ca vakṣyate' — the means will be spoken of. 'Buddhyatē anayetīti buddhiḥ' — buddhi here is that by which one is discriminatively known; 'sāṅkhya-viṣayo yāyā vācā budhyatē' — that is the meaning of the wording.
