Lind slowly grasped the truth about the Eternal Realm. The basics were essentially correct.
A Divine Realm Master Tier essentially had to take in a massive amount of energy and sever all connection to his Divine World. Only by taking that step could the transformation begin.
The massive energy, with nowhere to go any longer, would fuse the 9 Mysteries via the harmony into a new Path Power. It would literally become the quality of power defined by the fusion of harmony and Mystery.
However, the mind was part of the harmony. The Intent was essential to all cultivation skills or Arts. The Intent, however, had to come from the source alone. The Eternal Realm was no longer able to simply accept the biological limits of the brain.
The flesh was transformed by the energy and the essential pieces that make the cultivator who they are are distilled by the harmonic Qi as it is pulled into the dantian.
