The sound of one hand clapping

Dragonfly has been a close friend of mine online for some time now. I think we know each other well. We were exchanging thoughts about Masters and slaves recently. She wrote the following to me which I quote with her permission:

"And about D/s.... the ultimate Master is one who can let go of ego completely, thus in a sense becoming a slave.. and the ultimate slave is one who can let go of ego completely, thus in a sense becoming the Master... It is the sound of one hand clapping.. get it? There is no distinction between Master and slave.. they are one ego less entity.. they are one hand.. clapping... To force yourself into one or the other is the fallacy. I think that is what you struggle with as well.. You can be nurturing and subservient and dominate all at the same time. "
