Heroism Played Out

Campbell, in arguing against the "happily ever after" conclusion, outlines several outcomes for the hero on pages 36-37:

"The return and reintegration with society, which is indispensable to the continuous circulation of spiritual energy into the world, and which, from the standpoint of the community, is the justification of the long retreat, the hero himself may find the most difficult requirement of all.  For if he has won through, like the Buddha, to the profound repose of complete enlightenment, there is danger that the bliss of this experience may annihilate all recollection of, interest in, or hope for, the sorrows of the world; or else the problem of making known the way of illumination to people wrapped in economic problems may seem too great to solve.  and on the other hand, if the hero, instead of submitting to all of the initiatory tests, has, like Prometheus, simply darted to his goal (by violence, quick device, or luck) and plucked the boon for the world that he intended, then the powers that he has unbalanced may react so sharply that he will be blasted from within and without - crucified, like Prometheus, on the rock of his own violated unconscious. or if the hero, in the third place, makes his safe and willing return, he may meed with such a blank misunderstanding and disregard from those whom he has come to help that his career will collapse."

Is there no satisfying ending for the hero?  Is the longevity of memory all that he can hope for?
