The essence of submission is what is referred to as the "power exchange" in the lifestyle. The basic lifestyle definition being that power and control are exchanged between partners with one person taking control and having the power, while the other partner gives up control.
In our vanilla lives, giving up control is not a distant state from the extremely popular goal of Mindfulness or a mental state achieved by focusing one's awareness of the present moment. The only difference being, that in addition to existing in the moment, the submissive partner also cedes all control which frankly enhances one's mindfulness to just be; to just follow; to just obey.
Taken together, being in a D/s scene, with a skilled Dom and wanting submissive, can be one of the most satisfying personal experiences possible on a mental, emotional, physical and sexual level.
