For me, it's the part during the Last Battle where the woman tell Logain she will send her son to the Black Tower to be tested for the gift. Logain finally get's his purpose and glory, restores all that was once taken from him. The balance between Male and Female is finally restored, the past is wiped away and a brighter future is apparent. WoT could have ended there and I'd have been happy. Rand may have been the tool to drive the story, but Logain was the one to heal the rift with the common man.
