The Hidden Span, by Eliot Weinberger

The Taoist universe is an infinity of nested cycles of time, each revolving at a different pace, and those who are not mere mortals pertain to different cycles. Certain teachings take four hundred years to transmit from sage to student; others, four thousand; others, forty thousand. It is said that Lao Tzu, the author of the Tao Te Ching, spent eighty-one years in the womb. 

Taoist ritual begins with the construction of an altar that is a calendar and a map of this universe. At its perimeter, twenty-four pickets, the Twenty-Four Energy Nodes, each representing fifteen days, form a year of 360 days. Within, a proliferation of markers for the Two Principles (yin and yang), the Three Energies, the Three Irrational Powers, the Five Elements, the Five Tones, the Six Rectors, the Eight Trigrams, and Sixty-Four Hexagrams of the I Ching, the Nine Palaces and the Nine Halls, the Ten Stems of the Twelve Branches…Each is a supernatural being, a gate, a direction, a part of the body, a measurement of time, a philosophical concept, an alchemical substance. As Lao Tzu said, “The Tao created one, one gave birth to two, two to three, and three to the ten thousand things.”

Typically of Taoism, this system has an inherent flaw: a hole in time called the Irrational Opening. If, at a certain moment, which is always changing, one walks backward through the various gates in a certain order, one can escape time and enter the Hidden Span. In this other time beyond all the other times, one finds oneself in the holy mountains; there one can gather healing herbs, magic mushrooms, and elixirs that bring immortality. 

The technique was first taught to the Yellow Emperor by the six calendrical Jade Maidens, who in turn learned it from the Mysterious Woman of the Nine Heavens, also known as the Lady of the Ultimate Yin. Its most famous practitioner was a very real military strategist, Chu-ko Liang (181-234). To repel an invading army, he placed hidden markers on an enormous plain to secretly replicate a Taoist altar, and then tricked the enemy troops into entering through a certain symbolic gate. Although the landscape appeared unremarkable, the army found itself trapped in a labyrinth of an alternate time from which it could not escape.
