Shloka 29
आत्मदर्शन-उपदेशः (Ātma-darśana Upadeśa) — Mind, Senses, and the All-pervading Self
एतां द्वादशसाहसत्रीं युगाख्यां कवयो विदु: । सहस्रपरिवर्त तद् ब्राह्मं दिवसमुच्यते,इस प्रकार देवताओंके बारह हजार वर्षोका एक चतुर्युग होता है; यह विद्वानोंकी मान्यता है। एक सहस्र चतुर्युगको ब्रह्माका एक दिन बताया जाता है
etāṃ dvādaśasāhastrīṃ yugākhyāṃ kavayo viduḥ | sahasraparivarta tad brāhmaṃ divasam ucyate ||
ヴィヤーサは語った。「賢者たちは知っている。『ユガ』と呼ばれる時代の量は、神々の一万二千年に当たる。かかる四ユガの循環が千たび巡れば、それが梵天（ブラフマー）の一日と宣される。ゆえにこの教えは、人の時を広大な宇宙の秩序の中に据え、諸時代の興亡のただ中にあっても、謙虚さとダルマへの堅固さを促すのである。」

Educational Q&A
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.
