I will not let this thread die!!
I was thinking about just this issue earlier, as relates to my Master. My Master focuses me. He is very precise, very sharp and penetrating. I, however, am a never-ending expanse of largely disorganized thought and feeling. I spread out on every side. And when I am with him, I focus, almost to a laser point, as he is. And in that focus, I can truly use my thoughts and abilities to their fullest potential. And when he in the presence of my expansive chaos of thought, he has the creativity to push me to my limits.
We are implosion and explosion, yin and yang, black and white. To create all the possibilities of the universe, you need to have an equilibrium of both extremes.
That is what BDSM and submission mean to me. It is a meeting of two opposite minds, which enhances both.
