Then next aphorism is janmādy asya yataḥ (SB 1.1.1). Janma, ādi, asya, yataḥ. "From whom," asya, viśvasya, "of this universe, cosmic manifestation," from where this cosmic manifestation has come, and where it rests, and where it will dissolve. Janmādy asya yataḥ. In this way, Vedānta-sūtra means . . . gives you the whole purpose of Veda, knowledge, in small code words.
So to understand these code words, one must have very big brain or very highly standard educational qualification. Then . . . all the ācāryas, those who are controlling Vedic civilization, like Śaṅkarācārya, Madhvācārya, Rāmānujācārya, they have all written their commentaries on the Vedānta-sūtra. Because unless one explains Vedānta-sūtra, he'll not be accepted as an authorized ācārya. He's not . . . not that anyone can become ācārya. He must give explanation of the Vedānta-sūtra, prasthāna-traya. There is system.
So ultimately, Vedānta-sūtra, as Kṛṣṇa says, vedaiś ca sarvaiḥ. Sarvaiḥ means including Vedānta-sūtra. Vedaiś ca sarvair aham eva vedyam (BG 15.15): "I am to be understood." Why? Vedānta-kṛt vedānta-vit ca aham. Vedānta-kṛt, "I am the compiler of Vedānta-sūtra." The Vedānta-sūtra was compiled by Vyāsadeva. He is incarnation of Kṛṣṇa, Dvaipāyana Vyāsa.
So therefore, it is compiled by His incarnation, so it is compiled by Him. Because His incarnation, He is the same. So vedanta-kṛt means Veda . . . compiler of the Vedānta, and the compiler of the compiler of the Vedānta is vedanta-vit, one who knows Vedānta. Because I have written some book, so I know what is the purpose of writing my book. You cannot know. My purpose you cannot know.
