Something that may not be simply understood about how one sleeps is that one is actually recharging their spirit's energy as they sleep.  This occurs, I think...while one's energy spends time on the Astral Plane in dream state.  This came to mind concerning how I have been sleeping incorrectly, and how I can actually feel totally fine with very little sleep, yet, still keeping my body in shape.  The feeling of fatigue between the spirit and the body is...intertwined.  If the body goes on for too long without proper rest, it seems that a whole bunch of things get slowed down.  At the same time, if the person's spirit does not get the proper recharge, it will continue to try to press a person more towards literally falling asleep more so than to stay awake.  In that way, a person can have too much rest of their body and not enough of the spirit, but at the same time, vice versa.  A person should be more careful about that aspect, in that this can lead to a much larger imbalance within themselves.  At the same time, the physical self should not be allowed to have any strength over the spiritual self, such that sleep is only performed for the recharge of the spiritual self, and one should awaken their physical self as well, regardless of how they may think they "feel" upon waking up.

Something else that has come to mind is about how the spirit is also very closely intertwined with the different physical organs in the body.  Thus, if the spirit is in need of recharge, the organs in a person's body will be similarly drained, which can cause what might be seen as a decrease in the body's metabolism.  If the chakra meridians and all other aspects of a person's spirit are more in line and in tune, as well as balanced, and the flow of one's spiritual energy is in sync with Father Yahweh's manner of balance for all things, then a person may be less apt to be sick, feel better, and everything about the individual may be increased in efficiency all over, such that it doesn't take long for a person's body to adapt to physical strain, such as exercise, amongst other things.

It is also realized, in this, that there are many things about a person's chakra meridians that are dependent on others to stimulate properly.  In this...  The unconditional love aspect of one's heart meridian requires others to love.  If this is...hindered because of one's own thoughts or reasoning, the heart meridian incurs sickness and pain.  If continually ignored, it can become worse, and lead to self destruction.  At the same time, this can occur with any other meridian, and one area lacking can cause a further deterioration of the whole being.  There can be a bad imbalance amongst it all.  Fortunately, Father doesn't allow for Her servants to just be annihilated left and right due to a lack of solution to their heart's desires...which is multifaceted.  One should never seek to fulfill their own desires out of their own choices and solutions, but fully wait for Father for any solution to any desire they may have.  And endure doing so.  Otherwise, one may only seemingly satisfy their desire, but they really won't be, and only continually transgress against God, as well as just create imbalance within themselves.  Sin creates imbalance.  Period.
