Specifically by this process
of absorption with reflection
and absorption beyond reflection
the perception of
subtle objects can be accurately described.
The process of subtle perception
extends to that
which is without form
and is pure consciousness.
In both savichara samapatti (absorption with reflection) and nivichara samapatti (absorption beyond reflextion) one has knowledge or understanding of the subtle aspects of objects or experiences.
Iyengar explains that savichara samapatti is ?contemplation on subtle objects such as the ego (ahamkara), intelligence (buddhi) or the counterparts of the elements or tamatras (sound, touch, sight, taste and smell), or the qualities of luminosity, vibrancy, and dormancy conditioned by space, time, and causation.? (p. 91) Swami Satchidananda explains that the perception of subtle objects ultimately ends in ?the primal force called the Prakriti, or the primordial basic substance in its unmanifested condition. In that condition there is no name, no form, no thought, only the fully balanced, tranquil unmanifested state of nature. So the mind has the power to go to the very root of unmanifested nature.
Nivichara samapatti, is a ?state without verbal deliberation. All subtle objects reflected in savichara are extinguished. He (the sadhaka) is free from memory, free from past experiences, devoid of all past impressions. This new state of contemplation is without cause and effect, place or time.? (p.91)
I suppose in nivichara samapatti, the sadhaka is one with the subtle aspect in the same way that in nivitarka samapatti, the sadhaka is one with the object.
