These are my thoughts on why Alexander teaches us not to end-gain to fix localized conditions or problems, but instead apply the means-whereby that begins with the more beneficial carriage of the head in relation to the spinal column.
I have been thinking about AT as a tool for change: When you improve conditions through the head/neck/back and begin to function in a way where they are integrated, your perception of situations change as your sensory appreciation becomes more accurate and reliable. This change in perception is where AT facilitates the greatest change of use. It’s not about better body mechanics, or posture, or more refined coordination on a purely movement based, motor behavior level. It’s about totality, the constellation of perception and action relative to how we experience the world through our use, that affords us the most profound level of change, healing and transformation. We can respond more effectively and masterfully to the stimuli we meet.
