Appendix (Part 3)
One thing is established from this discussion of the history of philosophy; even though the testimony of the Vedas is necessary for all the three matas, since natural variation in the tendencies of human intellect worked independently, differences of opinion naturally arose in Vedanta. Difference in mati (intellect) is the main reason for difference in mata (opinion). Difference in intellect is the difference in capability, and variation in its tendencies is born out of its interaction with the manas.
