As some here may have noticed, I am rather fond of the Avatamsaka Sutra and its principal exponents. Should you find a good translation of a Huayan text, please put it in this thread.
I know of Cleary's small collection Entry Into the Inconceivable; several versions of Fazang's Golden Lion; this Vorenkamp version of Fazang on the Awakening of Faith and not much else.
General studies of Huayan like Cook's or Chang's et al do not interest me.
One should refrain from biased judgments and doubting in fathoming the Buddha and the Dharma of the Buddhas. Even though a dharma may be extremely difficult to believe, one should nonetheless maintain faith in it. Nagarjuna
