In H.v.Glasenapps article “The Influence of Buddhist Philosophy” I find the following sentence:
The two Russian scholars, Theodore Stcherbatsky, and his pupil, Otto Rosenberg, have shown that the doctrine of the “dharmas,” i.e. impersonal soul forces, is the central philosophical conception which is at the bottom of all Buddhist philosophical thought. The great Belgian indologist, La Valle Poussin, has dealt more minutely with the problem in his magnificent translation of Vasubandhu’s Abhidharmakoṣa. We understand now why the celebrated stanza “ Ye dharmaḥ hetuprabhāvaḥ ” is the credo of all Buddhists.
I couldn’t find this “Ye dharmaḥ hetuprabhāvaḥ” simply using google, however he assigns this phrase quite a basic importance. So what does it mean? Is this just the “I take refuge to the dharma”?
