Some people will ask: if all things do not exist, why are we able to perceive them? This is because we perceive them incorrectly. Why is that? Our eye consciousness is also tainted by ignorance and is therefore subject to error.

This point can easily be established. For instance, apart from motion which is readily apparent in a fire, river current, etc., our eyes see all things as basically motionless. Actually, all matter is composed of very small particles. These particles are in a constant state of flux, arising and ceasing each instant, even if measured in only one millionth of a second. There is nothing that stands still in this world. As such, why do we not see it? This illustrates the problem we have with our eyes. They are obstructed by ignorance and thus cannot see the true face of matter. If they cannot perceive the truth at this level, the more profound nature of reality is even harder to discern.
