Letters to Yaha is an early epistolary novella by William Burroughs. It is a logical continuation of "Junkie", which ends with the words "Maybe it all ends on a yacht." In letters to Allen Ginsberg, then an unknown young poet in New York, Burroughs describes his journey into the Amazon jungle, detailing the colorful incidents accompanying the search for telepathic -hallucinogenic-consciousness-expanding local drug Yahe (Ayahuasca or Bannisteria Caapi). This drug was used for ritual purposes by local shamans, sometimes to find lost objects, bodies or even the souls of people. The author and addressee of these letters met again in New York at Christmas 1953, selecting and editing a number of letters for publication as a book. This correspondence contained the first glimpses of Burroughs's later fantasy, which formed the basis of Naked Lunch. Seven years later, Ginsberg writes from Peru to the old guru an account of his own visions and experiences with the same drug and asks for advice. Burroughs' mystical answer came immediately. The book also includes two epilogues - a short note by Ginsberg, indicating that his "I" is still on this earth, and a final poetic cut-up by Burroughs, "Am I Dying, Mi-ister?"
