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, the 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.
