Due probably to my growing senility I forgot to mention: Rolf Stein, Avalokitezvara/Kouan-yin, un example de transformation d'un dieu en deesse, in Cahiers d'Extreme-Asie 2 (1986): 17-80 [with English summary]. As one would expect, Stein's paper is exhaustive and detailed, -- and reliable! Jonathan SILK jonathan.silk at yale.edu
