Phase Transitions in Subjective Experience

SUBJECTIVE EXPERIENCE 

In a thinking state of mind (random thinking as well as concentrated thinking):

The light reflected from the object impinges on the retina of the eye (the impingement or intial perturbation is called 'pratyaya' in yoga psychology) and creates a representation of the object. According to present-day neuroscience, this neural representation is encoded in the firing activity of neurons in the brain. The mind equivalent of such a representation in yoga psychology is 'vritti' /modification of the mind. There are neural correlates of the representation in the brain that can be measured. 

But then the question arises, what gives the human being, a feeling or experience of the object in the field of vision, as opposed to a camera/recorder that records the picture of the object? 

The neural representation of the object in the field of vision could be due to a 'phase transition', which results from the firing of neurons so that an image is generated on the retina of the eye. The image is the 'phase transition product', whose neural correlates could be the altered metabolic state/signaling circuit within neuronal cells, and/or wiring pattern between neuronal cells. 

The process of image generation/neural representation/vritti requires energy.  Vrittis /modifications of the mind are a series of phase transitions that could result from synchronous and /or asynchronous firing of neurons in the brain. In an ordinary mind, when random thoughts are generated, phase transitions are erratic i.e.  regulated pattern of phase transitions do not  occur, resulting in fluctuating vrittis.   Since a  human not only sees the object but feels it, (the redness of red), the feeling of aliveness of the experience of seeing the object i.e. the vrittis,   are illumined by  "Pure Consciousness/ Brahman"- the Universal energy field underlying spacetime and hence everything within it. This field is at equilibrium/still, but when illuminating the world of experience appears to be in motion i.e. energetic, because it is superimposed by mental activity i.e.pratyaya+vrittis.

In a concentrated thinking mind, phase transitions of the mind stabilize into a regular pattern, resulting in the flow state.

Pure Consciousness/Brahman, which illuminates the individual mind is manifested as Self-Awareness.

In a Meditative  Mind (During objective meditation on a name, sound-symbol):

Since during meditation (via yoga methods), mental activity is stilled (pratyaya+vritti are stilled)  phase transitions of the mind gradually stabilize into a regular pattern (flow state) as in concentrated thinking, then diminish slowly.  

Going deeper into meditation, phase transitions recede away. This is called ' Chitta Vritti Nirodh', or 'No mind' in Yoga psychology. Since mental activity/mind is not involved, no thoughts, feelings, cognitive biases are involved. Pure Consciousness/Brahman directly illuminates the nature of the object of meditation.  This is 'knowing' in the first person via meditative experience. This is the direct perception of the object of meditation, without interfering mental activity.

In a Meditative Mind (During subjective meditation on the Self/Subject itself)

Only Pure Consciousness/Brahman remains. Everything else is an appearance in Brahman.
