Perception of Time and Space.

[zenmaster]

Ra's declartion that 3D lacks understanding must be qualified to mean understanding in the sense of noumenal understanding. We do indeed "understand" within the limits that our abstractions provide. We work with practical and philosophical knowledge of tentative abstractions of perceived phenomena and ways of being. You can explain thunder as angry gods or air vibration due to electrical discharge. With either understanding, there is inherent sufficiency due to the satisfaction provided. Some people find satisfaction in more distortion, some with less. Remember, with certain "understanding" you can build "free energy" devices which can provide more leisure time and with certain "understanding" you simply can not.
