As we get deeper, more relaxed and settled, and are able to tune into momentary processes, we see that even with something that remains – in remaining, it is coming and going, arising and passing. For example, you might hear a constant rustling of the leaves in the tree in the wind, and say, "Oh, it's rustling all the time. It is constant." But in fact, the rustling – if you tune into it – is a lot of small little rustle sensations of leaves coming and going. The aggregate we take to be more of a continuous, solid thing.
