It is absolutely essential to try to figure out how you experience thoughts, otherwise you will simply flounder in content. What do thoughts feel like? Where to they occur? How big are they? What do they look like, smell like, taste like, sound like? How long do they last?

Where are their edges? Only take on this practice if you are willing to try to work on this level, the level that tries to figure out what thoughts actually are rather than what they mean or imply.

If my thoughts are somewhat auditory, I begin by trying to perceive each syllable of the current thought and then each syllable’s beginning and ending. If they are somewhat visual, I try to perceive every instant in which a mental image presents itself. If they seem somewhat physical, such as the memory of a movement or feeling, I try to perceive exactly how long each little sensation of this memory lasts. This sort of investigation can actually be fairly easy to do and yet is quite powerful.

Things can also get a bit odd quickly when doing this sort of practice, but I don’t worry about that. Sometimes thoughts can begin to sound like the auditory strobing section of the song “Crimson and Clover,”

where it sounds like they are standing at a spinning microphone.

Sometimes the images in our head can begin to flash and flicker.

Sometimes our very sense of attention can begin to strobe. This is the point! The sensations that imply a mind and mental processes are discontinuous, impermanent.

Again, this practice requires steadiness and determination, as well as precision. When I am really engaged with this, there is no time to be lost in the content of the thoughts, as I am trying too hard to be clear about the beginning and ending of each little flicker, squawk and pulse which makes up thought. This can be an especially fun practice when difficult thoughts are distracting me from a physical sensation. I can turn on them, break them down into meaningless little blips, little vibrations of suchness, and then they don’t have the power to cause me any trouble. They just scatter like confetti. They are seen as they are: small, 24

quick and harmless. They have a message to convey, but then they are gone.

When I am done with this exercise, I return to physical objects and their arising and passing. However, I have found taking on the sensations that make up thoughts to be another very useful exercise for developing concentration and penetrating the illusion of continuity. It doesn’t matter if they are “good thoughts” or “bad thoughts,” as all mental sensations are also dripping with ultimate truth that is just waiting to be discovered, and thus I can proceed in my investigation with confidence regardless of what arises. Whether our illusions are penetrated using physical sensations or mental sensations is actually completely irrelevant.

Hopefully these exercises will give you some idea about how one might practice understanding impermanence. Impermanence is a true mark of ultimate reality, so just understanding this again and again can be sufficient to drum it into our thick heads, debunk the illusion of continuity, and once this is drummed into our thick heads we are free.
