Cutting through in Zen Buddhism

We have to envision our thoughts as water-like vortices and change our habit of just seeing the shape (rupa) and proceed to look for the substance. We also have to envision that this water is utterly invisible and immaterial it is not a vortex. Then we have to face our everyday world as being a three dimensional field of vortices—then look for that special water. This is the way you cut through.
