IS

First experience the Is-ness of the gap between 2 moments of thought, then the Is-ness of the thought between 2 moments of gap.

Even if those who begin to practice this find it difficult to continue in this state for more than an instant, there is no need to worry about it. Without wishing for the state to continue for a long time and without fearing the lack of it altogether, all that is necessary is to maintain pure presence of mind, without falling into the dualistic situation of there being an observing subject perceiving an observed object.

If the mind, even though one maintains simple presence, does not remain in this calm state, but always tends to follow waves of thoughts about the past or future, or becomes distracted by the aggregates of the senses such as sight, hearing, etc., then one should try to understand that the wave of thought itself is as insubstantial as the wind. If one tries to catch the wind, one does not succeed; similarly if one tries to block the wave of thought, it cannot be cut off. So for this reason one should not try to block thought, much less try to renounce it as something considered negative.

In reality, just as there is no distinction whatever between the sun and its rays, or a stream and its ripples, so there is no distinction between the mind and thought. If one considers the calm state as something positive to be attained, and the wave of thought as something negative to be abandoned, and one remains thus caught up in the duality of accepting and rejecting, there is no way of overcoming the ordinary state of mind.
