Deussen 2010, p. 42, Quote: "Here we have to do with the Upanishads, and the world-wide historical significance of these documents cannot, in our judgement, be more clearly indicated than by showing how the deep fundamental conception of Plato and Kant was precisely that which already formed the basis of Upanishad teaching"..

Edward Roer (translator), Shankara's Introduction, p. 3, at Google Books to Brihad Aranyaka Upanishad at pages 3-4; Quote - "(...) Lokayatikas and Bauddhas who assert that the soul does not exist. There are four sects among the followers of Buddha: 1. Madhyamicas who maintain all is void; 2. Yogacharas, who assert except sensation and intelligence all else is void; 3. Sautranticas, who affirm actual existence of external objects no less than of internal sensations; 4. Vaibhashikas, who agree with later (Sautranticas) except that they contend for immediate apprehension of exterior objects through images or forms represented to the intellect."
