For a proper tonal everything on the island of the tonal is a challenge. Another way of saying it is that for a warrior everything in this world is a challenge. The greatest challenge of all, of course, is his bid for power. But power comes from the nagual , and when a warrior finds himself at the edge of the day it means that the hour of the nagual is approaching, the warrior's hour of power.
One bids for power and that bidding is irreversible. I wouldn't say that at the time power comes, that one is about to fulfill his destiny, because there is no destiny. The only thing that can be said then is that, at that point, one is about to fulfill his power.
