आत्मदर्शन-उपदेशः (Ātma-darśana Upadeśa) — Mind, Senses, and the All-pervading Self
एतां द्वादशसाहसत्रीं युगाख्यां कवयो विदु: । सहस्रपरिवर्त तद् ब्राह्मं दिवसमुच्यते
etāṃ dvādaśasāhastrīṃ yugākhyāṃ kavayo viduḥ | sahasraparivarta tad brāhmaṃ divasam ucyate ||
विद्वान कहते हैं कि देवताओं के बारह हजार वर्षों का यह ‘युग’ कहलाता है; और ऐसे (चतुर्युग-चक्र के) एक हजार आवर्तनों को ब्रह्मा का एक दिन कहा गया है।
व्यास उवाच
Cosmic time is measured in vast cycles: a yuga is reckoned as twelve thousand years of the gods, and a thousand such yuga-cycles make one day of Brahmā. The ethical implication is to cultivate detachment, patience, and commitment to dharma despite the immense, cyclical nature of worldly change.
Vyāsa is explaining a cosmological doctrine of time-reckoning—how yugas are counted and how they aggregate into Brahmā’s day—within the Shānti Parva’s broader instruction on order, duty, and the structure of the universe.
