They have no meaningful connection to the rhythms of life on Earth or to the movement of the cosmos. Time itself is both the Source and the destination of the physical, material world. All things are born in time, sustained by time and reclaimed by time. Time is fundamental. Control of time is the bottom line issue of mind control, soul control and spiritual liberty.
Calendars are the human language of time and timescape.
The way we view time permeates everything we think and do. Our current calendar and clock were quite consciously created to ignore the rhythms of Heaven and Earth. Because of this, they have served admirably to destroy the sacred bridge that links Heaven and Earth. Living within their dictate of time, humanity's instinctual connection to Nature has also been destroyed. This is Why we need a revolution in time.
