Joseph Pilates called his method Contrology.
He said to concentrate is vitally important.
To concentrate you must listen.
To listen you must observe.
Observe is not to think.

Machu Picchu is an observatory of planetary movement.
Pilates is an observatory of biological movement.
Observation occurs in a time continuum.
Observing time becomes the issue.
Perceiving change over time is what the observer is about.

At Machu Picchu their observation of planetary movement gave them insight to when to plant their crops. Their survival depended upon perceiving change and the advantage that gave them in surviving by having successful harvests.

In Pilates the observation of biological movement influences the quality and likelihood of survival. Observation of time for the perception of change equals survival. Time becomes the issue to achieve control.

We use frequency to measure time.
Tick tock, of the clock
The current tick tock of the clock for humanity is measured by the natural resonance frequency of the cesium atom (9,192,631,770 Hz). The frequency is used to define the second.
When you point a laser at cesium atoms they emit light, a state known as fluorescence. The observation time is only limited by the force of gravity pulling the atoms to the ground.
Longer observation times lead to better realization and control.

The situ of Machu Picchu led to longer observation times for better recognition of transition.  For instance, the occurrence of the summer solstice. The concentration in Pilates leads to longer observation for better realization of control.

To participate in the Michael Miller Pilates Convention come to Boulder..., or where ever you are know what time it is: http://www.time.gov/timezone.cgi?Mountain/d/-7/java

Exhale on Tuesday, June 21st 2011 at 11:15:55 AM Rocky Mountain Time. Five seconds before the planetary change: wait, listen, observe. Listen to feel the earth change the tilt of its axis. After 11:16:05 Rocky Mountain Time release your exhale to inhale into “your intention to fulfill your destiny.”
