Sanatana Dharama - I like this explanation
Sanatana Dharama - I like this explanation True knowledge of whatever sort was necessarily part of the fundamental truth of the Veda (or, for Buddhists and Jains, of their own sacred principles). Again, it would be misleading to characterize Indian thought simply as “static” or “timeless.” It changed over time to accommodate new ideas and new lines of argument, but innovations were generally worked into existing traditions rather than flaunted as revolutionary novelties. - Prof. Kim Plofker, Mathematics in India. http://nraonid.blogspot.com/2012/12/22-december-national-mathematics-day.html
