People who had used psychedelics reported that the experiences strengthened or created a passionate, protective connection with nature. Those already close to nature felt psychedelics re-established and deepened that bond; those without a prior connection said psychedelics helped them form one. Central to these shifts were transpersonal experiences, especially a sense of interconnectedness, which was most often linked to changes in attitudes and behaviors. Participants also noted benefits of having the experience in a natural setting. The findings suggest psychedelics can foster a caring relationship with nature even in people not previously nature-oriented.
This paper examines transpersonal psychology and ecopsychology together, focusing on their relationship with mystical experiences and the effects of nature-induced mystical experiences on ego-boundaries and psychological wellbeing. It argues that the re-emerging study of psychedelics—as positive agents for mental health, wellbeing, spiritual and creative growth, and social change—belongs inherently to a transpersonal ecopsychology. The paper concludes with a critical evaluation of these concepts and their implications for modern psychology.
