He went on: "With our limited senses we are, in a way, merely peeping out of little slits in an armored conning-tower of life, out at the stupendous vibratory battles of the cosmos.

Other creatures, in other planets, no doubt have other sense-organs to absorb other vibratory ranges.

Their life-experiences are so different from ours that we could not possibly grasp them, any more than a blind man could understand a painting.
"Nor could those creatures understand human life.

And what we cannot understand, though it is all perfectly natural, we call religion, the supernatural, God." From a great vacancy, the Master's words proceeded.
