Lokapramāṇa–Grahamaṇḍala–Dhruvaloka-vyavasthā
Cosmic Measures and the Arrangement of the Heavenly Spheres
सनत्कुमार उवाच । रविचन्द्रमसोर्यावन्मयूखा भासयंति हि । तावत्प्रमाणा पृथिवी भूलोकस्स तु गीयते
sanatkumāra uvāca | ravicandramasoryāvanmayūkhā bhāsayaṃti hi | tāvatpramāṇā pṛthivī bhūlokassa tu gīyate
Sanatkumāra said: As far as the rays of the Sun and the Moon indeed illumine, so far extends the measure of the Earth; that region is sung of as Bhūloka (the earthly world).

Cosmic Event: Cosmographic definition of Bhūloka by the reach of solar/lunar illumination
It frames human experience (Bhūloka) as the illumined, knowable field of worldly life—within which the bound soul (paśu) seeks the Lord (Pati). Recognizing the limits of the worldly domain supports vairāgya and turns attention toward Shiva as the transcendent liberator.
By defining Bhūloka as the realm of light and perception, it implicitly contrasts the measurable cosmos with Shiva, who is worshipped as Saguna through the Liṅga within the world, yet is ultimately beyond worldly measures as the supreme Pati.
A practical takeaway is to perform daily Shiva worship at sunrise or moonrise—japa of the Pañcākṣarī (Om Namaḥ Śivāya) with dhyāna on Shiva as the light behind all lights—using bhasma (Tripuṇḍra) and rudrākṣa as supports if one follows Shaiva observance.
