Vedas . . . the . . . in the Bhagavad-gītā it is said, vedaiś ca sarvair aham eva vedyaḥ (BG 15.15): "All the Vedas and Vedāntas, they are meant for understanding Kṛṣṇa." If by studying Vedas and Vedānta you cannot understand Kṛṣṇa, then it is śrama eva hi kevalam (SB 1.2.8). It is simply labor. That is the adjustment of Bhagavad-gītā and all other Vedic literature. Vedas means . . . Veda means knowledge, and anta means ultimate. That is called Vedānta.
So ultimate knowledge is to know God. You may not accept Kṛṣṇa, although all the ācāryas . . . I have already mentioned. Even Śaṅkarācārya, he also accept Kṛṣṇa: sa bhagavān svayaṁ kṛṣṇa. So the Rāmānujācārya, Madhvācārya, they have all accepted Kṛṣṇa: the ultimate knowledge of Vedic understanding. Many ācāryas, they have written notes on Vedānta, targeting Kṛṣṇa as the Supreme Personality of Godhead.
So we have to follow the footprints of the great stalwart ācāryas. Ācāryopāsanam. Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). If we follow the footprints of the ācāryas, then we find there is no distinction between Vedānta and Bhagavad-gītā. Vedānta, you might be referring to the Vedānta-sūtra of Śaṅkarācārya, but all the ācāryas, they have written notes on Vedānta.
Śrīmad-Bhāgavatam is the original comment on Vedānta. Śrīmad-Bhāgavatam begins with the Vedānta-sūtra: janmādy asya yataḥ (SB 1.1.1). So Vedānta does not mean godlessness. Vedānta means to know God. That is real study of Vedānta.
