Seeing thoughts, the reason why thoughts weaken or even disappear is because the power of thoughts comes from our identification and involvement. When a person is completely immersed in thoughts and takes "I am anxious" or "I am angry" as the true self, the thoughts will occupy consciousness and drive emotional and physical reactions; but when we begin to "see" the thoughts, that is, become aware of "I am generating an anxious/angry thought," we detach ourselves from the thoughts, shifting from participant to observer. The thoughts become objects of observation, and their control diminishes accordingly.

Just like the relationship between waves and the sea, thoughts are like brief ripples. When awareness returns to the overall level of consciousness, these ripples no longer have the overwhelming power; they are also like mud and silt in muddy water—disturbing it more makes it muddier, but simply observing quietly allows it to settle naturally. It’s also like characters and spectators in a play—when you are the character, you are completely carried away by the plot; but when you become the spectator, the story still unfolds, but the emotional pull is significantly weakened.
In terms of specific methods, it involves naming the thoughts to distinguish "me" from "the thought," then observing the physical sensations they bring without creating stories. The key is not to oppose or eliminate the thoughts, because trying to eliminate them is still a form of reinforcement. The true approach is continuous awareness: when a thought comes, see it come; when it stops, see it stop; when it leaves, see it leave. Do not assign meaning or intervene to control. In this way, the automatic pull of thoughts gradually weakens, and a person shifts from being controlled by thoughts to a state dominated by awareness.
