Yoga-kṛtya (योककृत्य) — Vyāsa on Sense-Restraint, Obstacles, and Brahman-Realization
सधर्मव्रतसंयोगं यथाधर्म युगे युगे । विक्रियन्ते स्वधर्मस्था वेदवादा यथागमम्
sadharmavratasaṃyogaṃ yathā dharma yuge yuge | vikriyante svadharmasthā vedavādā yathāgamam ||
毗耶娑说道：“在每一个时代（瑜伽，yuga），正法的行持与誓戒之修（vrata）的结合，皆依该时代之法而成形。然而当正法从一劫递一劫衰微之时，即便是安住于自身本分（svadharma）、言说契合吠陀者，也会随之发生变易——依经典为那变迁之世所制定的规范而调整。”

Educational Q&A
Dharma is not presented as a single unchanging social expression across all ages; rather, practices like vows and ritual life align with the dharma appropriate to each yuga. As the yugas progress and dharma diminishes, even sincere, Veda-aligned people are affected by that shift and must follow what scripture prescribes for the altered conditions.
Vyāsa is explaining a yuga-based framework of ethical and religious life: how righteous practice appears in each age and how the decline of dharma across yugas leads to changes in conduct, even among those devoted to svadharma and Vedic authority.
