I will sound like a broken record, but if "the [...] response to the essence of being [...] ends in sorrow or grim resolve" one is not yet "there". The journey ends with peace. One cannot miss it as it's obvious as night and day. One may return to sorrow, grim resolve, and even terror, but only to amuse oneself, in other words, out of personal preference, if one feels like it. Similarly, if one is able to sell-out one's "revelatory insights", such person has yet to see the final, liberating truth. Yes, somewhere along the way, one may feel "estranged from all nets and networks, faithless, humiliated, and stripped of cognitive weapons", but once one arrives, those feelings subside--"that too shall pass" as they say. And I can assure you, there's no way one would want to forget "encounter with one's true self" and return to limbo even if it was possible.
