It reminds me of what is said, that "talking is different than walking".
By substituting "talking" with "thinking" one can be led to suggest that a person may think as a slave or feel as a slave but that does not mean this person would be able or willing to "jump into the knees" as soon as Master enters the scene.
On the other hand, if one does not feel or think like a slave all the time, then how can one obey when not in obedience mood? How can one feel the Dominant's will to be obeyed and comply to this will, if not inclined to do so by inner feelings and thoughts?
My understanding is that acts of submission like obeying against own will or contarty to call of the moment to do something else are based on an inner, lets say rule, that gets internalised in the submissive person, slowly, and creates or sustains the need to obey and serve.
Maybe, i am wrong, YMMV. But that's how i feel it.
It makes stronger the submissive person as well but maybe it is the acceptance of the act by the dominant that creates this effect![]()
