When you look at the nature of any thought that arises, it automatically disappears by itself and a bare absence dawns. Likewise, when you inspect mind’s nature when it is settled, a non-obstructive bare absence and clarity is vivid. You see that the settled and moving minds are mixed together. Thus, no matter what thought arises, when you recognize that it is a movement of mind and, without blocking it, have settled on its nature, [you find] it is like the example of a bird confined on a boat. As is said, “Just as a crow having flown from a ship after circling the directions must re-alight on it….”
From cultivating such methods as these, you experience the nature of the totally absorbed mind to be a non-obstructive lucidity and clarity. Not established as any form of physical phenomenon, it is a bare absence which, like space, allows anything to dawn and be vivid. Such nature of mind must in fact be seen straightforwardly with exceptional perception and cannot be verbally indicated or apprehended as a “this”. Therefore, without such apprehension, settle in a fluid and flowing manner on whatever cognitive dawning arises.
