I have to say that for me, i have an almost visceral response to the word 'submission'. I just don’t like the word, as i feel it holds many negative connotations and feelings of forcefulness. I’m uneasy about any state of mind that might be considered submissive, as it plays into the hands of a hierarchical system, and makes me feel more of a prisoner than it does uplift and spiritually fulfil me. Which makes me less connected or inspired by the quotations as yourself. I would like to have seen some kind of MRI scan of my brain as i read those quotes, and compared it to yours reading them for the first time
One can understand why anyone would have an issue with the word submission. But then, this act is solely for those who truly desire to submit, and that phase comes usually somewhere in our lives where you just don't want to the submit to the system of this world subconsciously, and you need to liberate your inner sense of peace from all the material things surrounding you; you desire to belong to something beyond it, something forever and ethereal, just beyond it all.
In short, I could almost say that 'submission' is a bit of a misnomer, as it brings one of the most liberating feelings that one can go through, and it just sets you free, free, free. Nothing can compare to this freedom, Nothing.
Must say that one's spiritual status has to become receptive, extremely desirous for that submission to let it liberate you. If one is at a spiritual constant, lacking the conscious awareness of that 'need to submit', things wont happen. But one can always wish, who knows : )
