Awakening or enlightenment is not an understanding of the mind.
In fact, it is beyond the mind and all the tools of the intellect, like words and concepts.
Awakening is a fundamental shift in the perceptual framework of how Being, Infinite Consciousness, experiences itself through a flavor or point that prior appeared as a limited individual, but now is the One presence, which has always been.
Nothing has changed. Everything has changed. Changed beyond words.
