When locke describes his encounter with the monster with mr. eko he says that what he saw was a bright light yet that is not what eko saw or anyone else on the island. Earlier he describes to jack that he has looked into the island and what he has seen was beautiful. What did locke see that made him feel this way and what is this bright light? Is this why he was never scared of the monster? Could jacob be the bright light and the black smoke of the monster be his nemesis?
