“When the mind abandons its contact with the senses, including discursive thinking, the concentrated absorption of jhana begins.
The mind is utterly still and focused on its object.
.
.
The specific object of focus becomes progressively refined in the development of concentration, from the physical sensations of breathing, to a perception of light.
Rapture, pleasure, and equanimity may accompany the bright radiant mind, while attention is continually directed toward the place where the breath is known.
As these perceptions grow increasingly subtle, attention remains connected and the subtle perception of breath is recognized as a perception of stable brightness in mind.
In jhana, attention is virtually merged into its object, creating an impression of complete unification.
Even if there is sensory impact from sounds and sensations, the mind remains completely unmoved.
Sensory contact—even strong pain or loud noise—does not disturb the tranquillity or affect the unification of the mind with its object of concentration.
It is as though you don’t hear anything, yet the capacity of hearing is not impaired.
It is as if you don’t feel pain, and yet the bodily processes are functioning.
There may or may not be subtle awareness of the impact of a sound or physical contact, but the mind lets go so automatically that there can be no sensory residue to disturb the concentration.
