Ouroboros as described by Castaneda

I have no arguments with this description - it is just as I experience the Ouroboros:

"For the shamans of ancient Mexico, time was something like a thought; a thought thought by something unrealizable in its magnitude. The logical argument for them was that man, being part of that thought which was thought by forces inconceivable to his mentality, still retained a small percentage of that thought; a percentage which under certain circumstances of extraordinary discipline could be redeemed. 
Space was, for those shamans, an abstract realm of activity. They called it infinity, and referred to it as the sum total of all the endeavors of living creatures. Space was, for them, more accessible, something almost down-to-earth. It was as if they had a bigger percentage in the abstract formulation of space. According to the versions given by don Juan, the shamans of ancient Mexico never regarded time and space as obscure abstracts the way we do. For them, both time and space, although incomprehensible in their formulations, were an integral part of man. 
Those shamans had another cognitive unit called the wheel of time. The way they explained the wheel of time was to say that time was like a tunnel of infinite length and width, a tunnel with reflective furrows. Every furrow was infinite, and there were infinite numbers of them. Living creatures were compulsorily made, by the force of life, to gaze into one furrow. To gaze into one furrow alone meant to be trapped by it; to live that furrow. 
A warrior's final aim is to focus, through an act of profound discipline, his unwavering attention on the wheel of time in order to make it turn. Warriors who have succeeded in turning the wheel of time can gaze into any furrow and draw from it whatever they desire. To be free from the spellbinding force of gazing into only one of those furrows means that warriors can look in either direction: as time retreats or as it advances on them. 
Viewed in this manner, the wheel of time is an overpowering influence which reaches through the life of the warrior and beyond, as is the case with the quotations of this book. They seem to be strung together by a coil that has a life of its own. That coil, explained by the cognition of shamans, is the wheel of time."
