The Vedanta, then, practically forms the scriptures of the Hindus, and all systems of philosophy that are orthodox have to take it as their foundation. Even the Buddhists and Jains, when it suits their purpose, will quote a passage from the Vedanta as authority. All schools of philosophy in India,although they claim to have been based upon the Vedas, took different names for their systems. The last one, the system of Vyasa, took its stand upon the doctrines of the Vedas more than the previous systems did, and made an attempt to harmonise the preceding philosophies,such as the Sankhya and the Nyaya, with the doctrines of the Vedanta. So it is especially called the Vedanta philosophy; and the Sutras or aphorisms of Vyasa are,in modern India, the basis of the Vedanta philosophy. Again, these Sutras of Vyasa have been variously explained by different commentators. In general there are three sorts of commentators* in India now;



The commentaries are of various sorts such as the Bhashya,Tika, Tippani, Churni, etc., of which all except the Bhashya are explanations of the text or difficult words in the text. The Bhashya is not properly a commentary, but the elucidation of a system of philosophy out of texts,the object being not to explain the words, but to bring out a philosophy. So the writer of a Bhashya expands his own system,taking texts as authorities for his system.

There have been various commentaries on the Vedanta. Its doctrines found their final expression in the philosophical aphorisms of Vyasa. This treatise,called the Uttara Mimamsa, is the standard authority of Vedantism--nay, is the most authoritative exposition of the Hindu scriptures. The most antagonistic sects have been compelled, as it were, to take up the texts of Vyasa, and harmonise them with their own philosophy.
