Buddhabhadra, aka Batuo, this is a name i encountered recently.
I have yet to read anything by Dr. Yang addressing this person.
A person by the same name translated a great deal of vedic material into chinese over a thousand years ago. A person by the same name was also first abbot of Shaolin.
When you consider that Dao-mo, aka Bodhidharma is recorded as practicing martial arts in india, martial arts that use slow moving posture and stance based yoga as training tools, and that have animal styles... as well as meridian point striking... and when you consider that Batuo, a hindu man, was the founder of Shaolin... then history of origins becomes far more interesting...
