।।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।।
The word jyoti indicates illumination and is identified with the demigod known as Archi. This is confirmed in the Narada Purana which states: After reaching Agni the demigod of fire and then Archi the demigod of illumination and thereafter Ahah the demigod of day etc. It should be understood that Agni, Archi, Ahah and others are the presiding demigods of the respective time periods. Otherwise it would not be in accordance with the Vedic scriptures to say that during the daytime one reaches the bright waxing time of the month. The Brahma Purana states: Since in essence there only exists days which also includes nights, how can one situated in equanimity be said to have achieved the brahman only in the day during the bright waxing time of the month. So it is clear to the lucid that the presiding demigods in tandem with their corresponding time periods is the only logical interpretation in accordance with Vedic scriptures. The Garuda Purana states: The knowers of spiritual knowledge honor the presiding demigods of the respective time periods. Along with honouring the demigods such as Agni the fire god, Archi of illumination, Ahah of the day, Sukla of the waxing moon, Satmasah of the suns northern course and others, the presiding demigods of the Vishu or the passages travelled should also be honoured. The Brahma Vaivarta Purana states: Honouring the presiding demigods of the day, the night, the waxing and waning moons, the sun on its northern and southern course as well as the Vishu; one who has realised the brahman attains the Supreme Lord.
