The insight impressed on the mind by this cognition beyond reflection (Nirvicara Samadhi) checks other impressions (mind conceptions).
Asamprajnata Samadhi (non-distinguishable cognitive absorption) comes as a result of practiced Samprajnata Samadhi or cognitive absorption with focus on an object. Concentration on an object of reference followed by total absorption must be perfect before the object can disappear of its own accord and the mind is left to experience its own true nature as the light of consciousness itself. This state is Nirvicara Samadhi or cognition beyond reflection. There is no seed (hence the term Nirbija Samadhi) in the field of consciousness nor any new ones created (i.e. samskaras or mind-impressions). What remains is the pure I AM consciousness beyond object or qualities.
