Ego Two Steps Behind
The concept of nothingness, or emptiness, according to a massive overlap of Eastern mysticism, is about being natural and uncontrived for prolonged periods of time; almost absent from the moment; proactive for the potentiality of the next.
Emptying of the ego isn't a metaphor. The empty, pristine mind, not distressed by anything, is of great value to everything.
Wisdom is only knowledge until it is walked.
