I am in due receipt of your letter No. AR-2732 of the 26th ultimo, and I am very glad to note your frankness to admit that you cannot go so far at present to disseminate the basic principles of Indian philosophies.
Indian philosophies mean generally the Sada Darsana or the six different schools of philosophers namely, 1. the Mimamsa, 2. Sankhya, 3. Nyaya, 4. Mayavada, 5. Patanjal and 6. the Vedanta.
The last named Vedanta Darsana was compiled by Sri Vyasa after a thorough refutation of all other five Darsanas and therefore Vedanta is accepted by all Indian scholars and no body is recognized as bona fide who has no interpretation of this Vedanta Darsana.
