It appears this knowledge is not so secret after all.

there are many similarities in Silat to Hindu arts and also Tibetan Tantra. The postures, breathing, concentrian methods, the mental states or emotions etc.
I showed once Bon Po Tibetan Lama a Serak Djuru and his eyes got big and said that those are secret Mudras (hand postures) in Tibet! History shows us that the, hindus and Buddhist once occupied Indonesia. Most of the names in silat have sanskrit Hindu roots.
BTW, I meant corroboration with reflexolgy.
