Bhagavad-gita As It Is Lectures

Na pāvakaḥ means neither there is necessity of electricity or fire for illuminating because the spiritual sky is already illuminated by the brahma-jyotir.

Lecture on BG Introduction -- New York, February 19-20, 1966:

Now the description of that eternal sky... When we speak of sky, because we have material conception of the sky, therefore we think of sky with sun, moon, stars, like that. But the Lord says that the eternal sky, there is no need of sun. Na tad bhāsayate sūryo na śaśāṅko na pāvakaḥ (BG 15.6). Neither in that eternal sky there is need of moon. Na pāvakaḥ means neither there is necessity of electricity or fire for illuminating because the spiritual sky is already illuminated by the brahma-jyotir. Brahmajyoti, yasya prabhā (Bs. 5.40), the rays of the supreme abode. Now in these days when people are trying to reach other planets, it is not very difficult to understand the abode of the Supreme Lord. The abode of the Supreme Lord is in the spiritual sky, and it is named as Goloka. In the Brahmā-saṁhitā it is very nicely described, goloka eva nivasaty akhilātma-bhūtaḥ (Bs. 5.37). The Lord, although resides eternally in His abode, Goloka, still He is akhilātma-bhūtaḥ, He can be approached from here also. And the Lord therefore comes to manifest His real form, sac-cid-ānanda-vigraha (Bs. 5.1), so that we may not have to imagine. There is no question of imagination. The Lord's presence, by His causeless mercy He presents Himself in His Śyāmasundara-rūpa. Unfortunately, people with less intelligence deride at Him. Avajānanti māṁ mūḍhā (BG 9.11). Because the Lord comes as one of us and just like plays with us as a human being, therefore we need not consider that Lord is one of us. It is His omnipotency that He presents Himself with His real form before us and displays His pastimes, just the prototype of His abode. So that abode of Lord, there are innumerable planets also in that brahma-jyotir. Just like we have got innumerable planets floating on the sun rays, similarly, in the brahma-jyotir, which is emanating from the abode of the Supreme Lord, Kṛṣṇaloka, Goloka, ānanda-cinmaya-rasa-pratibhāvitābhis (Bs. 5.37), all those planets are spiritual planets.
