Translation: 
Candraśekhara continued, “There is no talk at Vārāṇasī other than discussions on the six philosophical theses. Nonetheless, Tapana Miśra has been very kind to me, for he speaks about topics relating to Lord Kṛṣṇa.
Purport: 

The six philosophical theses are (1) Vaiśeṣika, propounded by Kaṇāda Ṛṣi, (2) Nyāya, propounded by Gautama Ṛṣi, (3) Yoga, or mysticism, propounded by Patañjali Ṛṣi, (4) the philosophy of Sāṅkhya, propounded by Kapila Ṛṣi, (5) the philosophy of Karma-mīmāṁsā, propounded by Jaimini Ṛṣi, and (6) the philosophy of Brahma-mīmāṁsā, or Vedānta, the ultimate conclusion of the Absolute Truth (janmādy asya yataḥ), propounded by Vedavyāsa. Actually Vedānta philosophy is meant for the devotees because in the Bhagavad-gītā (15.15) Lord Kṛṣṇa says, vedānta-kṛd veda-vid eva cāham: “I am the compiler of Vedānta, and I am the knower of the Vedas.” Vyāsadeva is an incarnation of Kṛṣṇa, and consequently Kṛṣṇa is the compiler of Vedānta philosophy. Therefore Kṛṣṇa clearly knows the purport of Vedānta philosophy. As stated in the Bhagavad-gītā, whoever hears Vedānta philosophy from Kṛṣṇa is actually aware of the real meaning of Vedānta. The Māyāvādīs call themselves Vedāntists but do not at all understand the purport of Vedānta philosophy. Not being properly educated, people in general think that Vedānta means the Śaṅkarite interpretation.
