Yogi: When I breathe in and out, there’s a pause in between the two. And, in the gap, the mind will look for another object or wander off.

Sayadaw: You can be aware of the gap because it is also an object. The mind can know it because the meaning of an object is being known.

If you can understand that the gap is an object, the mind cannot wander off – the object and the awareness are there.

Because you think that the gap is not an object, you try to look for something else.
