Vedanta
Scripture
A theory that rests exclusively on human concepts may at some other time or place be refuted by arguments devised by cleverer people.... The conclusion is that with regard to supernatural matters, Scripture alone is the epistemic authority and that reasoning is to be used only in support of Scripture’ [Śrī Bhāṣya 2.1.12].
Metaphysics
Vedanta philosophies discuss three fundamental metaphysical categories and the relations between the three.
History
The history of Vedanta can be divided into two periods: one prior to the composition of the Brahma Sutras and the other encompassing the schools that developed after the Brahma Sutras were written. Until the 11th century, Vedanta was a peripheral school of thought.
