Ten thousand dharmas return to one. The name for this is the Absolute. If you open your mouth about the Absolute then you've already made a mistake. If you keep that point for a long time, then you see clearly, hear clearly, smell clearly, taste clearly, touch clearly, think clearly, and act clearly. Then, when you see, when you hear, when you smell, everything, just as it is, is the truth.
Truth is beyond time and space, cause and effect.
There are no opposites. This is the Absolute. If you attain this point, you attain the Truth. This world has a lot of suffering. The name for that is bodhisattva action.
