The best way to experience the illusory nature of things is through visual consciousness. When you close your eyes, you don’t see anything and therefore nothing seems to exist; when you open your eyes, everything appears immediately.
Hence, what you see is actually generated by your visual consciousness. Why is it that when our eyes are closed, there are no objects generated, but when they are open, objects arise? This is because, once light enters our eyes, our minds have the function to discern it, forming different objects and generating various images. Our eyes have a very high resolution, able to differentiate even slight differences. Therefore, they can clearly discern various things and generate visual objects. The same applies to sound. For example, when you play a recorder, what comes out are certainly sound waves. However, once these sound waves enter your ears, you turn them into sound, into music — it’s your auditory consciousness that turns them into music. In reality, there isn’t any music in the recorder, only electromagnetic waves are radiated. Be it a recorder or a radio, it’s just a machine. How could it speak? It merely emits sound waves. It is your own auditory faculty and consciousness that turn them into sound and music. Isn’t this illusory? This is exactly an illusion — you create them as if in a dream. This is an easy way to understand the illusory nature of things, that is, to meditate on the five consciousnesses of the eyes, ears, nose, tongue, and body, as well as the mind consciousness. Meditating on the illusory nature of the aggregate of consciousness is the easiest. In regard to the physical body, it is a bit more challenging. The physical body is flesh, so it’s relatively difficult to perceive it as dreamlike and illusory. Because our sense of it is too vivid: flesh can be consumed, and when cooked, it even has a taste — how can it be dreamlike and illusory? In fact, eating is also a kind of sensation. When you eat, it’s a sense of taste, which is discerned by your tongue. This is also an illusion. Without the six consciousnesses, you wouldn’t be able to perceive the aggregate of form — in particular, the nose consciousness senses odors, the tongue consciousness tastes flavors, and the body consciousness (the sensation of the body) experiences pain, pleasure, cold, and heat. The sensation of the body is actually a kind of discernment, like illusions. However, we tend to perceive this illusion as real, believing that the physical body truly exists. In reality, the physical body is like an illusion. We need to take our time to meditate on this — how do we exactly perceive the existence of forms? Without the six consciousnesses, we cannot perceive forms. This demonstrates that the aggregate of form is also illusory.
