As a Domina, I have to agree very much with what craven put forth. I feel when a slave and their Mistress (or Master) have a strong bond, there is an unspoken understanding and trust that is key between them. I feel the term "blind obedience" is one that can be viewed and interpreted in various ways, and it is up to the two people involved to first set the boundaries, and know one another wholly and completely so that those boundaries are not broken. I myself do not wish for a mindless slave....it would be like dominating a robot...and that is not what I want out of a D/s relationship. (personally)
Then again, I am not your typical Domina...so it is my personal opinion. I enjoy having a slave who has a mind of their own, yet is obedient, loyal, honest, and trustworthy, and yet is self sufficient, not depending on me for everything.
