There are a lot of names that help identify how the body works.
But once you see how it works you need to follow routines, rituals and practices.
This may seem counter intuitive because these systems have evolved over long periods of time and we must learn to trust them and keep them on in better ways.
Can you see the body needs to survive?
When we are in danger, it automatically goes into the sympathetic nervious sytem which is part of the autonomic nervous system.
Basically, this fight or flight system allows the body to run away or stay and fight through the obstical.
The parasympathetic nervous system is also part of the autonomic sytem.
It will feed and breed or rest and digest.
This optimum situation only happens when there is no danger or circumstance to fight or flight.
Together these two sides of the nervous system automatically allow the body to work its best.
Nature has made us this way and it is up to us to learn, understand and allow our body to reach its optimum state.
