Any "Chronicles of Thomas Covenant" fans here? [View all]

I read both the First and Second Chronicles twice, years ago, and am trying to remember a particular scene in one of the Second Chronicles books, very possibly in White Gold Wielder. One of the people (or beings?) in the final push to save The Land sacrifices himself to help the others and as they cry out to him, he says something to the effect of, "It's not my life that matters, but LIFE."

This line has been resonating in my mind for quite a while lately and I feel it's very relevant today. Does anyone remember that scene and better yet, which book I can find it in?

Thanks in advance!
