Dear Walter,

My congratulations also on this impressive accomplishment.

Contrary to a still-prevailing misconception, the 10th-century Mokṣopāya from Kashmir has nothing at all to do with Śaṅkara's Advaitavedānta  . . .

 
Was the existence of  Śaṅkarācārya and/or his writings known in 10th century Kashmir?

Thanks,
Harry Spier
