In fact, you don’t have to run after the proliferating mind. Really, it just moves around its own enclosed circuit; it spins around in circles. This is the way your mind works. It’s samsāra vatta – the endless cycle of birth and death. This completely encircles the mind. If you tried pursuing the mind as it spins around would you be able to catch it? It moves so fast, would you even be able to keep up with it? Try chasing after it and see what happens… What you need to do is stand still at one point, and let the mind spin around the circuit by itself. Imagine the mind was a mechanical doll, which was able to run around. If it began running faster and faster until it was running at full speed, you wouldn’t be able to run fast enough to keep up with it. But actually, you wouldn’t need to run anywhere. You could just stand still in one place and let the doll do the running. If you were to stand still in the middle of the circuit, without chasing after it, you would be able to see the doll every time it ran past you and completed a lap. In fact, if you did try running after it, the more you tried to chase after and catch it, the more it would be able to elude you.
