As for non-reaction, one can recognize that it has been fully achieved when no attachment arises in regard to anything at all, whether perceived directly or learned.
When the ultimate level of non-reaction has been reached, pure awareness can clearly see itself as independent from the fundamental qualities of nature.
Later, after one practices steadily to bring all thought to a standstill, these four kinds of cognition fall away, leaving only a store of latent impressions in the depth memory.
Sickness, apathy, doubt, carelessness, laziness, hedonism, delusion, lack of progress, and inconstancy are all distractions which, by stirring up consciousness, act as barriers to stillness.
As the patterning of consciousness subsides, a transparent way of seeing, called coalescence, saturates consciousness; like a jewel, it reflects equally whatever lies before it - whether subject, object, or act of perceiving
These four kinds of coalescence - with thought, beyond thought, reflective, reflection-free - are called integration that bears seeds of latent impressions.
Unlike insights acquired through inference or teachings, this wisdom has as its object the actual distinction between pure awareness and consciousness.
