What is the ending in Junky by Burroughs?

The final brief segment of the novel sets up the future—the bizarre Künstlerroman draws to a conclusion with the matured and capable Bill Lee mastering junk and alcohol, looking forward to new frontiers in ever more-distant lands. Bill has been stripped of all support systems, his nationality, his culture, his health, his family, even his language, and even his addiction. He remains a forty-something white man obsessed with homosexual desire and bodily pleasure brought about by altered states.
