Yoga–Sāṃkhya Synthesis, Chariot Allegory, and the Vyakta–Avyakta Distinction
तेष्वेवमादीनाचारानाचरत्सु विपर्यये

When those people, though instructed in such principles of right conduct and the like, act in the opposite manner—abandoning proper practice and turning toward its reversal—
शक्र उवाच
The line highlights a key ethical concern in dharma-literature: knowing or being taught proper conduct is not enough—when people act contrary to established right practice, disorder and moral failure follow. It sets up a contrast between dharmic norms (ācāra) and their violation (viparyaya).
Śakra (Indra) is speaking and describing a situation where individuals who have been associated with or instructed in proper codes of conduct nevertheless behave in the opposite way. The verse functions as a transitional clause, preparing for consequences, admonition, or corrective guidance in the surrounding passage.
