He realized that time, clocks ticking, everything is just a human-made concept. That clocks didn’t tick back in the times he was seeing now, and he realized that the sun never sets as long as you travel with it, circumnavigating the globe, once every 24 hours. It was a new thought, a new dogma to Jordan, evolving his idea of being more than one at once. It was an idea of being more than one time at once, literally moving along the 4th dimension. Not being pushed to the side, not being pushed up or down, not being pushed inward or outward, but being pushed in one way, without ever moving at all. They were being pushed along the track of time, with no way to go back, with no way to retract and go back to the starting point as they could in any of the three visible dimensions. And it was that thought, Jordan finally realized, that made him exhausted and scared. It was that realization that made Jordan realize that this was the thing Tong was afraid of. That through all his travels on planes and all his moving around the world, he could still go back to Bangkok, he could still go back to the hospital where he was born, but he could never go backward on that track and stand in the same place, only the same location, as where his first day began."-A Spontaneous Existence, Chandler Ivanko
Recollection of death also serves as a useful preparation for the time when one actually has to face death. As the concluding exercise among the body contemplations, a regular recollection of death can lead to the realization that death is fearful only to the extent to which one identifies with the body. With the aid of the body contemplations one can come to realize the true [impermanent] nature of the body and thereby overcome one's attachment to it. Being free from attachment to the body, one will be freed from any fear of physical death.
He thought back to everything that happened the night before: the hooded men, the chase, his tired heart and weak legs. The very moment in which Mathias realized it was over, when he'd decided to sacrifice his own life in order to save the young man by his side, the monk had found something fundamental inside himself. Deep in his soul, in that hidden place that can only be discovered when a person finds himself poised on the edge of the abyss, gasping what he thought was his last breath, he'd suddenly seen it. Only then did he realize what he held dearest in his heart. Because the last thing to cross his mind, what he'd thought about the moment he'd spun around, prepared to impale himself on the blade, had been a face. No thoughts of God or faith or any other saint. A face. That's when everything became clear.
