For advanced education there are various kinds of books of knowledge, such as the four Vedas, their six supplements, the Vedānta-sūtra, books of logic, books of religiosity and the Purāṇas. So all together there are fourteen divisions of books of education. Of these, the book which presents adhyātma-vidyā, spiritual knowledge — in particular, the Vedānta-sūtra — represents Kṛṣṇa.
Among logicians there are different kinds of argument. Supporting one's argument with evidence that also supports the opposing side is called jalpa. Merely trying to defeat one's opponent is called vitaṇḍā. But the actual conclusion is called vāda. This conclusive truth is a representation of Kṛṣṇa.
