May want to check out Master Nan Huai Chin's teachings, as Cundi practice is a core part of that.
Interestingly, Cundī in Tang esoteric manuals is nowhere called a manifestation of Avalokiteśvara. Cundī is an esoteric female deity of the buddha family, not the lotus family in Tang esoteric Buddhism. In ninth century Japan, Cundī (Jpn. Jundei, or Juntei) was first called a form of Avalokiteśvara by the Shingon monk Shōbō (832–909, 聖寶, aka Rigen Daishi 理源大師, only mentioned in passing here http://en.wikipedia.org/wiki/Daigo-ji
). Shingon practice follows two primary lineages, with the lineage of Shōbō specifically claiming Cundī as a member of the lotus family, while the other placing her in the buddha family. Tibetan practice places her in the buddha family as well. Thus, in Japan, the teaching of six manifestations of Avalokiteśvara (for the six gati) arising from esoteric Buddhism follows two forms: one with Cundī and one using Amoghapāśa instead.
I'm wondering if you can explain where the interpretation of Cundī as a manifestation of Guanyin comes from in China, and how far back it goes?
BTW, Master Nan Huai Chin's practice seems to be possibly Tibetan in origin, or at least not in the Tang esoteric tradition, FWIW.
