The depthless, fathomless, soaringly timeless, state of being arising when a person digs deep enough to leave body and mind behind and achieve what those two weaker vessels could not on their own.
An example, the night raid at Riva Ridge by the 10th Mountain Division in 1945, and digging deeper the next day against stiff resistance to take Mt. Belvedere:
This is relative to mental and physical conditioning, for the person with lesser conditioning, if their body then mind gives way earlier than those more advanced in body and mind training, the spirit kicks in sooner. And for the advanced athlete, warrior, whatever…later, perhaps.
Will we ever come to the point where we run, perform, act, compete, work, and achieve from this state of being from the beginning of the effort, mind and body moved efficiently from this zone in our being? That would be a breakthrough. What endurance, strength, and other qualities would be possible then? Where are the limits? I guess we really don’t know yet, and that is an exciting frontier that those of us in a boundary set world can escape to every day.
