“Psilocybin Can Occasion Mystical-Type Experiences Having Substantial and Sustained Personal Meaning and Spiritual Significance”

“Psilocybin Can Occasion Mystical-Type Experiences Having Substantial and Sustained Personal Meaning and Spiritual Significance” is a research paper the book identifies as a landmark in the psychedelic renaissance. Its importance in the available record lies in the claim framed by its title and in the book’s repeated placement of the paper among discussions of psychedelic research and experience. The wording is carefully qualified: it presents psilocybin as capable of occasioning such experiences, not as producing them invariably.

The Claim in the Title

The title combines a cautious causal phrase with a substantial description of the experience at issue. “Can occasion” signals a possibility or capacity rather than a guaranteed effect. “Mystical-type” names a kind of experience without, by itself, settling what metaphysical interpretation should be placed on it. The remaining phrase identifies the significance attributed to those experiences: their personal meaning is described as substantial and sustained, while their spiritual significance is also emphasized. These are the paper’s stated subject and claim as conveyed by its title; the available references do not supply its methods, results, or the evidence on which that claim rests.

Place in the Book

The book’s index directs readers to the paper at pages 10–11 and 29–30. It also calls the paper landmark when referring to the psychedelic renaissance, again pointing to pages 11 and 29–30. The repeated references mark it as a work the book returns to in presenting the renewed study of psychedelics, rather than a title mentioned only in passing. The index likewise associates the paper with ego dissolution, directing readers to pages 10–11 and 29–30. That cross-reference places the paper near a discussion of altered relations to the self, but the index alone does not establish exactly how the paper treats ego dissolution or what conclusions it draws.

Scope and Evidentiary Limits

The book’s references support a concise account: this is a landmark paper concerning psilocybin and mystical-type experiences, cited in connection with the psychedelic renaissance and ego dissolution. They do not provide enough information to describe the study’s participants, procedures, measures, findings, or later influence in detail. Nor do the title and index references establish that every psilocybin experience is mystical, that reported meaning necessarily persists for every participant, or that spiritual significance is being asserted as an objective supernatural fact. The title’s qualified language matters: it presents a research claim about the possibility and reported significance of a kind of experience, while the book’s repeated citations signal that claim’s importance within its account of psychedelic research.
