Adhyaya 46 — Cosmic Dissolution, the Emergence of Brahma, and the Measures of Time (Yugas, Manvantaras, and Brahma’s Day)
तत्प्रमाणैव सा रात्रिस्तदन्ते सृज्यते पुनः ।
एवंतु ब्रह्मणो वर्षमेकं वर्षशतन्तु तत् ॥
tat-pramāṇaiva sā rātris tad-ante sṛjyate punaḥ | evaṃ tu brahmaṇo varṣam ekaṃ varṣa-śataṃ tu tat ||
সেই রাত্রিও একই পরিমাণ; তার শেষে আবার সৃষ্টি সম্পন্ন হয়। এভাবেই ব্রহ্মার এক বছর; এবং তা একশ বছর পর্যন্ত প্রসারিত।
Creation and dissolution are balanced phases; the teaching encourages equanimity—seeing beginnings and endings as paired movements within a larger order.
Sarga and Pratisarga together: dissolution in Brahmā’s night and renewed creation at its end; also supports Manvantara by situating it within the kalpa framework.
Equal day/night indicates symmetry of manifestation and withdrawal; contemplatively, it suggests that silence (nirodha) is as foundational as activity (pravṛtti).
