I have just finished The Rainbow. My immediate understanding is that, at last, Ursula has a more detached perspective of existence: she can see that human life, despite all its materialism, its artificiality and the superficial changes, is, as ever, occurring within the natural perpetual cycle of death and rebirth. I think this suggests she can now appreciate a constant blend of 'Sunday' and 'Weekday' life... that she has reached an acceptance of the simultaneous presence of the infinite darkness that surrounds light. Any thoughts appreciated.
