Thomas Cleary uses the term "enlightening being" extensively in his translation of the Avatamsaka Sutra. This term isn't defined in the glossary of that book, or in my copy of The Princeton Dictionary of Buddhism. Is there a canonical definition of "enlightening being"?
Edit: Thanks useful comments by @ChrisW and @KayCee, I see in Appendix 1 "bodhisattva or enlightening being". I'm finding it helpful to read this Appendix before returning to the Introduction.
