About disappointment and sadness and other human indulgences - a GOAL worth striving towards, imo, is within "no things in mind, no mind in things" - since it is a goal, that implies it has yet to be achieved, at least on a permanent basis.
I've come to suspect "englightenment" itself is similar, in that it is not a constant but a sometime state of being. Therefore, at times, when having things in mind, mind in things (i.e. not enlightened) one can still recall the admonition and work towards re-attaining that state.
An ordinary man is Buddha: desire and passion is enlightenment. One thought of folly makes a man an ordinary man; the next enlightened thought and he is a Buddha.
Jed, at least in his books, appears constantly to be in the enlightened state, however, there's a chance when he was writing the books, that he may have "fallen out of grace" and done something stupidly human. Perhaps his editors ensured that got deleted.
I don't have his books any longer in any format, so I can't look up what you suggested. What came to mind, however, in regard death and rebirth is more along the lines of Buddhist theology in regard reincarnation, not a state of enlightened being.
