So far we are concerned, Madhva-Gauḍīya Sampradāya, our ācāryas, they took it, Śrīmad-Bhāgavatam, as the right commentary on Brahma-sūtra. Bhāṣyaṁ brahma-sūtrānāṁ vedārtha-paribṛṁhitam. This Śrīmad-Bhāgavatam is the real bhāṣya of Brahma-sūtra. So the Gauḍīya Sampradāya did not make any commentary on the Brahma-sūtra because they took it, Caitanya Mahāprabhu took it as, Śrīmad-Bhāgavatam, as a natural commentary, because Śrīmad-Bhāgavatam is also made by Vyāsadeva and Vyāsadeva is the original author of Brahma-sūtra. So author made his own commentary; so there was no need of another commentary. This is the Gauḍīya-siddhānta, Gauḍīya-vaiṣṇava-siddhānta.
But sometimes back, in Jaipur, there was a challenge that "The Gauḍīya Sampradāya has no commentary on the Vedānta-sūtra." So at that time Viśvanātha Cakravartī Ṭhākura was requested... Because he was grand scholar, grand old man scholar, at that time living in Vṛndāvana... So he was very old at that time; so he authorized Baladeva Vidyābhūṣana, that "You do it." There was no need, but people are demanding, "Where is your commentary on the Vedānta-sūtra?" So Baladeva Vidyābhūṣana, with the order of Govindaji at Jaipur, he wrote the commentary on Brahma-sūtra. That name is Govinda-bhāṣya. So the Gauḍīya-Brahmā Sampradāya, they have got also commentary on Brahma-sūtra. That is required.
