Here are some common Kundalini-related experiences and how neurobiology might interpret them. These explanations are hypotheses rather than established facts.

Energy moving up the spine

Many people describe a current, heat, vibration, or pressure rising from the base of the spine to the head.

Possible neurobiological factors:

• Increased awareness of normally unconscious bodily sensations (interoception).

• Activity in sensory pathways along the spinal cord.

• Changes in autonomic nervous system arousal.

• Muscle tension and release patterns creating waves of sensation.

Pressure in the forehead or crown

Some report sensations around the "third eye" or top of the head.

Possible factors:

• Tension in facial, scalp, and neck muscles.

• Changes in blood flow.

• Altered sensory processing in brain regions involved in body awareness.

• Increased attentional focus on specific body areas.

Bliss, ecstasy, or overwhelming love

This is one of the most commonly reported features of mystical experiences.

Possible factors:

• Changes in neurotransmitters such as dopamine, serotonin, oxytocin, and endorphins.

• Reduced activity in networks associated with self-focused thinking.

• Enhanced feelings of connection and emotional salience.

Related areas of study include Affective Neuroscience and Neurotheology.

Loss of ego or sense of self

People sometimes report that the boundary between themselves and the world dissolves.

Possible factors:

• Altered activity in the brain's "default mode network" (DMN), a set of regions linked to self-referential thinking.

• Changes in how the brain constructs the sense of a separate self.

• Similar patterns have been observed during deep meditation and some mystical states.

Spontaneous body movements (kriyas)

These can include shaking, jerking, unusual postures, or involuntary breathing changes.

Possible factors:

• Release of long-held muscle tension.

• Altered motor control and movement patterns.

• Interactions between emotional processing and motor systems.

• Heightened autonomic nervous system activity.

Inner lights, sounds, or visions

Some people report seeing light, hearing tones, or experiencing vivid imagery.

Possible factors:

• Activity in visual and auditory processing networks.

• Hypnagogic phenomena (states between wakefulness and sleep).

• Increased vividness of internally generated perceptions.

Why Federico Faggin became interested

Federico Faggin has argued that subjective experience ("what it feels like to be conscious") cannot be fully explained by neural activity alone. His transformative experience led him to investigate whether consciousness is fundamental rather than produced entirely by the brain. This remains a minority philosophical position rather than the consensus view in neuroscience.

What science can and cannot say

Science can:

• Measure brain activity.

• Study neurotransmitters and nervous-system changes.

• Compare meditation, mystical states, and ordinary consciousness.

Science cannot currently:

• Prove or disprove the spiritual interpretation of Kundalini.

• Explain exactly why subjective experience exists at all (the "hard problem" of consciousness).

• Determine whether consciousness is solely generated by the brain or reflects something more fundamental.

So from a neurobiological perspective, Kundalini experiences are real experiences that correspond to measurable changes in the brain and body. What those changes ultimately mean—purely neurological, spiritual, or both—remains an open question.
