There is a spiritual component to self-awareness that consists of expanding your consciousness through meditation, mindfulness, and other established spiritual practices. But in this list we wanted to tell people how to function efficiently in the mind-body feedback loop.
From birth each of us has been part of the loop, dependent upon it for all the good things in our lives, doing our best not to bring in bad things. But most people don't pursue self-awareness. They equate it with feeling bad about themselves, turning over stones that are best untouched, and exposing the darker hiding places where anxiety, depression, and anger lurk. None of this is true. Self-awareness is value-free. It isn't scary. It doesn't imply that you will subject yourself to needless pain.
At its most basic, self-awareness is simply self-appreciating the self. To find an answer to a question we are all interested in -- "How am I doing?" -- you have to be willing to look in the first place. It is much more beneficial to your health if you feel your way through life than think your way through life.
Self-awareness monitors how you feel. It is flexible, sometimes placing awareness on a bodily sensation, sometimes on the world around you, your relationships, the people you meet, the thoughts in your head, and so on. To be in such a state means that you are fully participating in the mind-body feedback loop. By doing so, you make your body and your brain into allies, and then the path to lifelong health can be followed in security and fulfillment.
