Both meditation and psychedelic drugs like psilocybin and LSD can disrupt the sense of self, but these disruptions are not uniform. Meditation traditions aim to dissolve the self through altered states, while psychedelics produce drug-induced ego dissolution via serotonin receptor agonism. The authors argue that self-consciousness is a multidimensional construct, with narrative aspects (autobiographical memory, self-related thoughts) and embodied aspects (multisensory processes) being differently affected by each. They caution against conflating temporary self-loss with long-term selflessness as a trait, though preliminary evidence suggests possible correlations. The article calls for nuanced understanding of these phenomena.

A selfless state of consciousness, reported for centuries in wisdom traditions, involves both temporary and lasting conditions. In psychology, the healthy self is typically emphasized, and the idea of selfless modes is sometimes dismissed, hindering empirical progress. This paper offers an interdisciplinary conceptual discussion grounded in the pattern theory of self (PTS), which views the self as a complex pattern of dynamically related processes. It proposes that meditative practices induce a reorganization of the self-pattern, enabling temporary or persistent selfless experience. The authors present a heuristic model, the pattern theory of selflessness (PTSL), with six nonlinear transformations: consolidating and integrating the self-pattern; cultivating concentration and present-moment awareness; cultivating mindful awareness; self-deconstruction states; self-flexibility; and self-liberation as a trait. This integrative view advances understanding of non-self experience and guides empirical research.

The pre-reflective sense of self, a tacit and constant feature of consciousness that frames the self as a bounded and embodied agent, is difficult to study empirically. Deep meditative states that dissolve this sense of self offer a path for investigation. In a phenomenological study, meditative self-boundary alteration was characterized by changes in six experiential features: sense of location, agency, first-person perspective, attention, body sensations, and affective valence. Quantitative analyses revealed a unitary dimension of boundary dissolution. Passive meditative gestures of “letting go,” which reduce attentional engagement and sense of agency, drove the depth of dissolution. These findings support an enactive approach linking the pre-reflective self to sensorimotor activity and attention-demanding processes.

Long-term meditators can intentionally reduce their sense of being an embodied agent, and this change corresponds to specific brain activity reductions. In a preregistered study, 46 experienced meditators (19 female, 27 male) used advanced meditation techniques to attenuate their embodied self-experience while undergoing magnetoencephalography. Those who reported radical disruptions—such as losing a sense of agency or a localized first-person perspective—showed reduced high-beta-band oscillations in the posterior medial cortices (PMC). These neural changes correlated with lifetime meditation experience and interview-based reports, but not with standard self-report questionnaires. The findings show that combining first-person methods with neuroscience can reveal how the brain supports the embodied sense of self.

The sense of being a bounded self can be attenuated or dissolved while awareness remains. Analyzing magnetoencephalography data from 46 long-term meditators, the study found that both meditation conditions (self-boundary dissolution and maintenance) increased broadband entropy rate and directed information transfer compared to rest, driven mainly by high-frequency activity. Localized reductions in information transfer from the anterior cingulate to posterior cingulate and in high-beta entropy rate in sensorimotor and posterior-medial cortices differentiated the two meditation conditions. Reduced orbitofrontal cortex entropy rate and reduced information transfer from occipital, cingulate, limbic, and subcortical areas correlated strongly with self-boundary dissolution phenomenology. Together with a previously reported neural correlate of reduced high-beta power in the posterior-medial cortex, these two neural correlates explained over half the variance in phenomenological dissolution scores (R² = 0.52).
