The New Signal Chakras & Subtle Body Anatomy was originally called The Survival Chakras & Subtle Body Anatomy. This was because they always indicated when some part of the body or being had gone into some form of ‘Survival’ mode.
They work as an ‘Alert’ system, signalling a quick warning in these body Chakras and providing a quick readout if there is ‘shut-down’ or some other form of overwhelm of energy is operating. Even something as basic as being in present time is so easily tested by locating a single point on the body!
