गोविन्द भाष्य (श्रील बलदेव विद्याभूषण - अचिन्त्यभेदाभेद वेदान्त ब्रह्मसूत्र भाष्य सटीक)

"At the time of death a person's knowledge, deeds, and concept of life combine to determine his future." This passage shows that knowledge and pious deeds both together determine the soul's future. Sūtra 6 tadvato vidhānāt tadvataḥ—like that; vidhānāt—because of the rule. Because of a rule like that. Purport by Śrīla Baladeva Vidyābhūṣaṇa In the Taittirīya-saṁhitā it is said: brahmiṣṭho brahmā darśa-paurṇamāsayos taṁ vṛṇīte "To perform the darśa and paurṇamāsa rites, he chooses a priest learned in the science of the Supreme." Thus it is clearly seen that transcendental knowledge is only a subordinate part of the Vedic rituals, for such knowledge only qualifies one to be a priest. Sūtra 7 niyamāc ca niyamāt—because of a rule; ca—also. Also because of a rule.
