I like Bhante Henepola Gunaratana and his discourses. One day I saw this:
I have no doubt this is absolutely true. Yesterday I came across another site which quotes the same (धर्मं रक्षति रक्षितः) from the मनुस्मृति.
It’s true that all the masters are saying the same thing. I don’t think it’s coincidence or repeats. There are some fundamental rules to this universe and no matter how many century passes by they seems to hold true. Why else the same thing that is said thousands of year ago is said again in the current generation.
