Adhyaya 79 — The Vaivasvata Manvantara: Classes of Devas, the Seven Sages, and Manu’s Nine Sons
भूर्लोकोऽयं स्मृता भूमिरन्तरिक्षं दिवः स्मृतम् ।
दिव्याख्याश्च तथा स्वर्गस्त्रैलोक्यमिति गद्यते ॥
bhūrloko 'yaṃ smṛtā bhūmir antarikṣaṃ divaḥ smṛtam |
divyākhyāś ca tathā svargas trailokyam iti gadyate ||
भूर्लोक पृथ्वी के नाम से प्रसिद्ध है; अन्तरिक्ष को आकाश/दिव कहा जाता है; और इसी प्रकार ‘दिव्य’ कहलाने वाला स्वर्ग—इन तीनों को त्रैलोक्य कहा गया है।
The Purāṇic narrative often anchors ethical discourse in cosmic order; by defining the three worlds, it frames dharma and governance as operating within a structured universe rather than a random world.
This is Sthāna (cosmic ‘place’/structure) embedded within Manvantara narration—typical of Purāṇas, where genealogies and reigns are contextualized by cosmography.
The threefold division can be read as a macrocosmic mirror of threefold experience (gross–subtle–causal), though the verse itself is primarily cosmographical.
