Distress is a signal. The cells of the body are communicating to the mind their oppression by the false self.
Unfortunately, the mind cannot do anything about the oppression of the cells. When it tries, all it does is prevent the distress signal from reaching its true destination.
Embodiment is liberation of the cells from the tyranny of the false self. But how does this happen? Not through revolution but through intervention.
For the enlightenment transmission to intervene, distress is necessary. Distress allows the signal to break through the mind-barrier between body and Soul and for connection to be restored.
