One last thing about vibrations: looking into vibrations can be a lot like any other sport. It can be thought of the way we might think of surfing or playing tennis, and this sort of game-like attitude can actually help a lot. We're “out to bust some vibrations!” as a friend of mine enthusiastically put it. You don't know quite what the next return or wave is going to be like, so pay attention, keep the mind on the pulse of the sensations of your world just as you would on the wave or ball, and keep playing!

I highly recommend this sort of speed in practice not only because that is how fast we have to perceive reality in order to awaken, but also because trying to experience one to ten sensations per second is challenging and engaging. Because it is challenging and engaging, we will be less prone to getting lost in thoughts rather than doing insight practices. Our minds have the power to perceive things extremely quickly, and we actually use this power all the time to do such things as read this book. You can probably read many words per second. If you can do this, you can certainly do insight practices.

If you can perceive one sensation per second, try for two. If you can perceive two unique sensations per second, try to perceive four. Keep increasing your perceptual threshold in this way until the illusion of continuity that binds you on the wheel of suffering shatters. In short, when doing insight practices, constantly work to perceive sensations arise and pass as quickly and accurately as you possibly can. With the 21

The Three Characteristics

spirit of a racecar driver who is constantly aware of how fast the car can go and still stay on the track, you are strongly advised to stay on the cutting edge of your ability to see the impermanence of sensations quickly and accurately.

I will relate four of the many little exercises that I sometimes do that I have found useful for jump-starting and developing insight into impermanence. They will demonstrate how we can be creative in exploring our reality precisely but hopefully they will not be thought of in some sort of dogmatic way. These objects and postures are not that important, but understanding impermanence directly is.

In one of these exercises, I sit quietly in a quiet place, close my eyes, put one hand on each knee, and concentrate just on my two index fingers. Basic dharma theory tells me that it is definitely not possible to perceive both fingers simultaneously, so with this knowledge I try to see in each instant which one of the two finger’s physical sensations are being perceived. Once the mind has speeded up a bit and yet become more stable, I try to perceive the arising and passing of each of these sensations. I may do this for half an hour or an hour, just staying with the sensations in my two fingers and perceiving when each sensation is and isn’t there. This might sound like a lot of work, and it definitely can be until the mind settles into it. It really requires the concentration of a fast sport like table tennis. This is such an engaging exercise and requires such precision that it is easy not to be lost in thought if I am really applying myself. I have found this to be a very useful practice for developing concentration and debunking the illusion of continuity. You can pick any two aspects of your experience for this exercise, be they physical or mental. I generally use my fingers only because through experimentation I have found that it is easy for me to perceive the sensations that make them up.
