Yoga-kṛtya (योककृत्य) — Vyāsa on Sense-Restraint, Obstacles, and Brahman-Realization
ऋषीणां नामधेयानि याश्च वेदेषु सृष्टय: । नानारूपं च भूतानां कर्मणां च प्रवर्तनम्
ṛṣīṇāṃ nāmadheyāni yāś ca vedeṣu sṛṣṭayaḥ | nānārūpaṃ ca bhūtānāṃ karmaṇāṃ ca pravartanam ||
Vyāsa said: “(He taught) the names and lineages of the seers, and the various emanations described in the Vedas; and also the manifold forms of living beings, together with the way actions are set in motion and come to operate.”
व्यास उवाच
The verse highlights comprehensive sacred knowledge: understanding Vedic accounts of creation, the authoritative tradition of the ṛṣis, the diversity of beings, and—ethically most crucial—the causal activation of karma (how actions begin to bear consequences).
Vyāsa is describing the scope of instruction or exposition being given: it spans Vedic cosmology and genealogy of seers, the variety of living forms, and the dynamics by which actions operate in the world—framing a dharma-oriented explanation of reality and moral causation.
