Yes – Tibetan sky-gazing meditation, a Dzogchen practice emphasizing open awareness, can reduce activity in the brain’s default mode network (DMN). Regular practice appears to shift neural patterns from self-focused rumination toward present-centered awareness, effectively “rewiring” how the brain constructs experience and identity.

Understanding The Default Mode Network
The DMN is a network of brain regions – especially the medial prefrontal cortex, posterior cingulate cortex, and angular gyrus – that activates when the mind drifts inward. It supports autobiographical memory, planning, and self-reflection. While essential for self-continuity, chronic DMN overactivity correlates with anxiety, depression, and intrusive thought patterns. Sky-gazing meditation directly targets this by training awareness to rest without fixation.
What Sky-Gazing Involves
Unlike focused-attention meditation, which concentrates on the breath or mantra, sky-gazing asks practitioners to maintain relaxed awareness of the open sky – vast, boundless, and luminous. The goal is not to analyze sensations but to experience pure presence without grasping. In Dzogchen, this is seen as recognizing the “natural mind” – uncontrived and spacious.
Neural Mechanisms Behind The Practice
Deactivation Of Self-Referential Circuits
Neuroimaging studies of open-monitoring and non-dual awareness practices show decreased DMN activation. The reduction in medial prefrontal activity corresponds to less self-judgment and narrative thinking. Simultaneously, connectivity increases between attentional and salience networks, enhancing sensitivity to the present moment.
Integration Across Networks
Over time, practitioners display greater coupling between the DMN and executive networks, suggesting more fluid transitions between introspection and action. This integration supports adaptability – one can think reflectively without becoming trapped in thought loops.
Neuroplasticity Through Stillness
Regular sky-gazing strengthens prefrontal regulation of limbic reactivity. As emotional triggers lose their habitual pull, amygdala activity decreases, creating a calmer baseline. This emotional quiet provides fertile ground for new neural patterns to form, particularly in areas governing attention and perspective-taking.
Subjective Effects And Phenomenology
Practitioners often report sensations of spaciousness, weightlessness, or boundary dissolution. These experiences correspond with reduced integration of bodily self-signals and diminished prediction error within sensory cortex – essentially, the brain stops insisting on the solidity of “me.” The result is a direct experience of awareness as vast and centerless, mirrored by the sky itself.
How To Practice Safely
- Environment: Choose a quiet outdoor spot with a clear view of the sky. Avoid harsh sunlight – early morning or dusk works best.
- Posture: Sit comfortably with eyes open but unfocused. Let visual awareness expand naturally rather than fixating on one point.
- Duration: Begin with 5–10 minutes. Over weeks, extend to 20 minutes as mental agitation decreases.
- Integration: After each session, briefly reflect on how perception felt – grounding abstract insight in memory helps the brain consolidate learning.
Evidence From Related Research
Though direct studies on sky-gazing are limited, related research on non-dual awareness (NDA) and open-presence meditation supports its effects. A 2019 NeuroImage study found long-term NDA practitioners exhibited lower DMN activity and increased connectivity between attention and sensory networks. EEG work shows reduced beta and increased alpha/theta coherence, reflecting relaxed alertness rather than dullness.
Psychological Outcomes
Consistent practice improves emotional regulation, creativity, and self-other distinction. Many participants note a shift from narrative self-reference (“I am thinking this”) to direct awareness (“thoughts are arising”). Over time, this translates into reduced reactivity, enhanced patience, and more flexible cognitive framing under stress.
Common Misconceptions
- It’s Just Relaxation: The calmness is a byproduct, not the goal. The deeper shift lies in how awareness relates to thought.
- Sky Is Required: The sky is metaphorical – its vastness cues the same openness achievable indoors through visualization.
- Instant Enlightenment: Neuroplastic change takes consistent practice; transient spaciousness does not equal permanent rewiring.
How The DMN “Rewires”
With repetition, resting-state fMRI reveals decreased DMN dominance and increased global efficiency – meaning information flows more freely across networks. This correlates with improved emotional equanimity and cognitive flexibility. Essentially, the brain learns to downregulate self-referential chatter and favor a balanced, panoramic awareness mode.
Tibetan sky-gazing meditation trains the brain to rest in openness, reducing default mode dominance and fostering integration across attention, sensory, and emotional systems. While not mystical in neurological terms, it offers a reliable route to quiet the mental narrator and experience awareness itself as the sky – spacious, clear, and free.
