Bhagavad Gita, Chapter 8, Verse 9

कविं पुराणमनुशासितार- मणोरणीयंसमनुस्मरेद्यः । सर्वस्य धातारमचिन्त्यरूप- मादित्यवर्णं तमसः परस्तात्

kaviṃ purāṇamanuśāsitāra- maṇoraṇīyaṃsamanusmaredyaḥ | sarvasya dhātāramacintyarūpa- mādityavarṇaṃ tamasaḥ parastāt

Translation

Whoso meditates on the Sage, the Ancient, the Ruler, smaller than an atom, the Dispenser of all, of unthinkable nature, glorious like the Sun, beyond the darkness, (whoso meditates on such a Being) at the time of death, with a steady mind endued with devotion and strength of Yoga, well fixing the life-breath betwixt the eye-brows, he reaches that Supreme Puruṣa Resplendent.

— Alladi Mahadeva Sastri

Śaṅkarācārya's commentary

Sage: the Omniscient. The Ruler: of the whole world. Dispenser: who allots to all living beings actions and their results in all their variety. It is very difficult for anybody to conceive of His form though it exists.
