We get information from the Bhagavad-gītā, the sun, sun planet, is not impersonal, not a lump of matter. There is the predominating deity in the sun globe, and his name is also given in the Bhagavad-gītā—Vivasvān. Vivasvān manave prāha (BG 4.1). Prāha, he explained Bhagavad-gītā. Therefore he's a person. As we get, get this experience that from the sun globe, within the sun globe there is a person, and, due to the effulgence of that personal rays of the sun god, or the population there, every people being glowing, the whole sun planet is so powerful, glowing, and the glow is distributed all over the universe, similarly, there is a glowing effulgence of the Supreme Person. That is called brahma-jyotir. That brahma-jyotir is impersonal, but the brahma-jyotir is resting on the Personality of Kṛṣṇa.
So ultimate Absolute Truth is Kṛṣṇa. That is the verdict of all Vedic literature, Vedānta, and Kṛṣṇa says that vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). Anyone who has not understood Kṛṣṇa, he has not studied the Vedic literature very perfectly. Vedānta-vid vedānta-kṛd ca aham, Kṛṣṇa says. He's the compiler of Vedānta. So who will know Vedānta better than Kṛṣṇa?
The so-called Vedāntists, they are very much proud of their knowledge of Vedānta, but the, the real compiler of the Vedānta philosophy is Vyāsadeva. He's incarnation of Kṛṣṇa. Therefore Kṛṣṇa says, vedānta-kṛd vedānta-vit. He is the compiler of the Vedānta-sūtra and He knows what is Vedānta-sūtra, not the so-called Māyāvādī philosophers.
So we have to learn Vedānta-sūtra from Kṛṣṇa, not from others. Not from others. We are not going to be befooled. We know what is Vedānta-sūtra. Vedānta-sūtra points out that "Here is the person, Supreme Person, Kṛṣṇa. Īśvaraḥ paramaḥ kṛṣṇaḥ." Brahmā says, īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ (Bs. 5.1). Kṛṣṇa Himself says, ahaṁ sarvasya prabhavaḥ (BG 10.8). He is the origin.
