Govinda is person. This impersonal Brahman, nirākāra, that is His personal effulgence, bodily effulgence. Just like the sun. You can understand. The sun planet is localized, and within the sun planet, there is sun-god. His name is also mentioned in the Bhagavad-gītā, Vivasvān.
- imaṁ vivasvate yogaṁ
- proktavān aham avyayam
- vivasvān manave prāha
- manur ikṣvākave 'bravīt
- (BG 4.1)
- evaṁ paramparā-prāptam
- imaṁ rājarṣayo viduḥ
- (BG 4.2)
So this is the process of studying Bhagavad-gītā.
So if you study Bhagavad-gītā and conclude that the Absolute Truth is nirākāra, I don't think you are making very much progress. Therefore Kṛṣṇa says, tad viddhi praṇipātena paripraśnena sevayā (BG 4.34). You try to understand this science by praṇipāta, praṇipātena, by surrendering, not by deserving yourself, that "I am very learned scholar. Why shall I surrender?" No. That is the first thing wanted. If you want to understand Bhagavad-gītā, then you must take the direction from the Bhagavad-gītā.
The first direction is, evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2): "All the rājarṣis, they understood Bhagavad-gītā by the paramparā system." That paramparā system, Kṛṣṇa also says, imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1): "I spoke first of all this system of yoga system in the . . . mentioned in the Bhagavad-gītā." That is bhakti-yoga. What is that yoga system? Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). This is the ultimate instruction of Bhagavad-gītā. Vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). "All the Vedas, they are teaching only to understand Me, Kṛṣṇa."
