There is a greatness the world can produce and a greatness only the awakened mind can know, and the two are not measured on the same scale. The best the ego offers still stands within the dream, preparing and pointing but not yet home, while the smallest thought that has entered the kingdom has crossed from illusion into truth. Rank inside the dream, however high, cannot compare with having woken from it.
A mind that grasps this stops striving to be the greatest figure in a story that is passing. It sees that the least place in reality outweighs the first place in a dream, because being awake is worth more than any honor sleep can give.
John the Baptist: the highest achievement possible within the dream, the herald who prepares the way yet still stands outside the waking.
The kingdom of heaven: the state of the mind that has remembered its oneness with God, the reality beyond the dream where even the least is whole.
