15. Actually this is brought out very well in the Christian Gospels. When Christ was led into the desert for his final purification (40 days and 40 nights) he was tempted by the devil with worldly power and riches.
This can be interpreted as a temporary valley experience of the kind I have mentioned representing the temptation to use one's considerable gifts in a self-serving manner.
We know of course that Christ did not succumb but rather took the much harder truly integral route that led to his extremely painful death.
However when we look at the way many religious sects operate we find that many of their leaders have indeed succumbed to this temptation.
