I agree with most of what you said, except I think you miss a core mechanism. Specifically, it doesn't just encourage non-thinking (though this is certainly an aspect), but it also encourages you to take a step back, and explore around what you are feeling. This is profound, because it very quickly leads to you figuring out chains of causality in yourself. You gain a much deeper understanding of why you do things, what you are like as a person, and what you could change in order to stop these cause and effect relationships. So, in essence, you get a root cause analysis for free, which gets built in to your muscle memory.
