Śrīmad-Bhāgavatam 1.5.4
Blended reading (Sanskrit + English inline)
The Vedānta-sūtra, or Brahma-sūtra, compiled by Śrī Vyāsadeva is the full deliberation of the impersonal absolute feature, and it is accepted as the most exalted philosophical exposition in the world. It covers the subject of eternity, and the methods are scholarly. So there cannot be any doubt about the transcendental scholarship of Vyāsadeva. So why should he lament?
Nor can you say that the reason for lamentation is lack of realized knowledge, because you have investigated and made conclusions in the Vedānta-sūtras about the eternal brahman that spreads everywhere in impersonal form. Not only did you inquire about brahman (jijṣāsitam), but you have understood and realized (adhītam) that brahman. Śrīdhara Svāmī says adhītam means understood or attained.
