As in the three fold space meditation, where we are trying to view space from the perspective of rigpa, here in Asanga's method we are trying to attend to the object from the perspective of the substrate. The substrate illuminates but does not enter into the object - no grasping. So we attend to the tactile field and within that field the sensations of the flow of prana correlated with the breath but without grasping. Alan also explains stage four of the nine attentional states leading to Shamatha. Here coarse excitation has stopped but the problems of medium excitation and coarse laxity are present.

Meditation starts at: A silent meditation session at 5:58, not recorded.
