Zhu Yi, many years ago, was able to come up with his own mantra with his understanding of light and darkness. Through cultivation, his understanding of the Heaven and Earth increased non-stop and eventually, he was able to obtain new changes.
Light brought brightness, and darkness brought dimness. The change of light and darkness was a supreme principle that dictated the change in the heaven and earth.
Brightness is visible and clear. It referred to all events and objects that could be known.
Dimness resides in the absence of light, rendering it impossible to see. It referred to everything that could not be understood or felt.
The combination of the two of them referred to the unification of all one knew and one did not know, of everything that could be seen and could not be seen.
