अग्निर्ज्योतिरहः शुक्लः षण्मासा उत्तरायणम्।
तत्र प्रयाता गच्छन्ति ब्रह्म ब्रह्मविदो जनाः।।8.24।।
।।8.24।। जो ब्रह्मविद् साधकजन मरणोपरान्त अग्नि ज्योति दिन शुक्लपक्ष और उत्तरायण के छः मास वाले मार्ग से जाते हैं वे ब्रह्म को प्राप्त होते हैं।।
Time in this verse indicates the route where the presiding demigods over the various time divisions from the day up to a year, reside in great numbers. Their route is either that path going by which yogis or those perfecting the science of the individual consciousness attaining communion with the ultimate consciousness are not subject to rebirth; or that path where persons of righteous deeds are born again. This last path Lord Krishna is describing now. The mention of fire, illumination, day, waxing moon and the suns six month sojourn on its waxing northern journey implies the year as well.
