I believe there are already several threads on the Forum regarding The Hero's Journey. I would like to very briefly interpret that journey in a slightly different way here. That's because it so happens this is also the soul's (true) journey, over and over, throughout all of our life. (I suggest that's why we like to watch movies or plays or read novels or watch TV talent competitions and so on -- to remind us of, and also to reflect from a distance on, what we ourselves are really doing.)
Practically all that we believe we know is built out of what's in our collection of memories. All of that is (precisely) our conditioning. Yes, some of our conditioning (such as professional skills) may quite often serve as a good thing. But life is also continually confronting us with so many critical situations or intense problems to which our conditioning and our education has no answer, at all. Like the hero forced to journey far out of his comfort zone, our mind once again throws its hands up, so to speak, unable to see any reliable way ahead. And yet, like the hero, we obviously must take a blind leap of faith at this point, knowing that the mind will probably not be so lucky as to now somehow hit on the right answer by accident.
Welcome to the world of the soul, where the unknown becomes a very joyful place to adventure in. This is where the mind finally stops searching, because navigating the unknown is beyond its capabilities. Like the hero, it's only when the mind has put everything aside completely, letting the consequences be damned, that the momentum of all the conditioning, of the whole world of the known, can come to a complete stop. The end of all that the mind thinks to be permanent (yet which is all impermanent). The dark night of the mind (and not of the soul, despite what St John of the Cross may have said). Only then does what the intuition, the soul, (holistically) sees and creates as the obvious but novel and ingenious solution, come shining through or bursting forth. This is why the soul is sacred.
