That's the world of emptiness. If we have time and space, then all things exist. If we transcend time and space, then we come to the world of emptiness. Taking one more step, we come to the world of truth. In the world of truth everything we see, hear, smell, taste and touch is always teaching us.
Every moment is truth.
This is the world of truth. If somebody says that they found which is correct then this heavy Zen stick will hit you thirty times. Yes, there is a correct world. But, if you say that you found it, this stick will hit you thirty times. If you say you cannot find it, then this stick will also hit you thirty times.
