नारद–शुक संवादः
Impermanence, Svabhāva, and Śuka’s Resolve for Yoga
चलां तु प्रकृतिं प्राहु: कारणं क्षयसर्गयो: । आक्षेपसर्गयो: कर्ता निश्चल: पुरुष: स्मृत:
calāṃ tu prakṛtiṃ prāhuḥ kāraṇaṃ kṣaya-sargayoḥ | ākṣepa-sargayoḥ kartā niścalāḥ puruṣaḥ smṛtaḥ ||
阎若婆迦说道：“自性（Prakṛti）被称为‘动’，因为它是毁灭与生成二者的因基。补卢沙（Puruṣa）则被忆念为‘不动’——就投射与显现而言为其主宰与作用者——而在创造与收摄的诸过程发生之时，仍恒常不变。”

Educational Q&A
The verse distinguishes two principles: Prakṛti is changeful and serves as the causal ground for creation and dissolution, while Puruṣa is essentially unmoving/unchanging, associated with agency in manifestation without itself undergoing transformation.
In Śānti Parva’s philosophical instruction, Yājñavalkya explains a Sāṅkhya-style framework to clarify how cosmic processes (sṛṣṭi and pralaya) relate to the material principle (Prakṛti) and the conscious principle (Puruṣa).
