Verse
कविं पुराणमनुशासितारं अणोरणीयंसमनुस्मरेद्यः ।सर्वस्य धातारमचिन्त्यरूपम्- मादित्यवर्णं तमसः परस्तात् ॥
This supreme Self is the Seer, the Ancient of Days, subtler than the subtle and (in his eternal self-vision and wisdom) the Master and Ruler of all existence who sets in their place in his being all things that are; his form is unthinkable, he is refulgent as the sun beyond the darkness; he who thinketh upon this Purusha in the time of departure, with motionless mind, a soul armed with the strength of Yoga, a union with God in bhakti and the life-force entirely drawn up and set between the brows in the seat of mystic vision, he attains to this supreme divine Purusha.
Gītā 8·9
