The System of the Vedanta according to Badarayana's Brahma-Sutras and Cankara's Commentary c5.s2.t2.19

c5.s2.t2.19

And here we touch the fundamental want of the Vedânta system, which, among other things, causes the absence of its proper morality, however near this, in its purest form, lay to its principle.³⁶ Rightly the Vedânta recognises, as the sole source by which we may reach true knowledge, true apprehension of being-in-itself, our own "I," but it wrongly halts at the form in which it directly appeals to our consciousness, as a knower, even after it has cut away the whole intellectual apparatus, and ascribed it to the "not I," the world of phenomena, just as it has also, very rightly, indicated as the dwelling of the highest soul, not, as Descartes did, the head (about which Brih. 2, 2 treats), but the heart.
