Investigating Hypo-Egoic Features: Ayahuasca's Psychedelic Path Versus Meditation's Mindful Journey

Area of Science:

• Neuroscience
• Psychology
• Contemplative Science

Background:

• Ego dissolution involves a temporary state of reduced self-reference and boundary dissolution.
• Both psychedelic substances like ayahuasca and contemplative practices such as meditation are thought to modulate the ego.
• Ayahuasca induces transient alterations in self-perception, while meditation fosters sustained changes via cognitive and emotional regulation.

Purpose of the Study:

• To investigate whether ayahuasca consumption modulates the ego.
• To compare the effects of ayahuasca with those of meditation on ego modulation.
• To examine the relationship between cumulative practice and ego modulation.

Main Methods:

• A total of 37 ayahuasca users and 137 meditators were assessed.
• The Delusion of Me (DoM) index, a self-report measure of acceptance, decentering, and non-attachment, was used to assess ego modulation.
• DoM scores were analyzed in relation to ayahuasca consumption and meditation practice.

Main Results:

• Meditators reported significantly higher DoM scores compared to ayahuasca users.
• No cumulative effect of ayahuasca sessions on DoM scores was observed.
• Meditation practice showed a significant non-linear association with DoM scores.

Conclusions:

• Meditation practice is associated with enhanced ego modulation.
• Cumulative meditation practice demonstrates a significant non-linear relationship with ego modulation.
• Repeated ayahuasca exposure did not show a cumulative association with ego modulation in this sample.
