This made me think that believing in a self is evolutionarily advantageous, but perhaps illusory. Those who don't associate their body and life as their "own" in some metaphysical sense will be substantially more prone to dying before reproducing.
How is someone who believes in private cloud, with zero remote management, observationally distinguishable from one that is OK using 100% public cloud? The answer is related to how they establish trust within their organization and themselves based on their use cases.
Some Tibetan Buddhist monks practice a type of mindfulness that consists of imagining bits and pieces of their bodies are being slowly dissolved or devoured, until nothing is left. They trust their 'souls' are actually a part of a higher consciousness that they seek to become aware of through their actions, and death. These monks definitely prohibit certain actions to attain their intent. Drugs, sexual desire, right thinking, right action, right mindfulness, etc. You can totally tell the difference from them and someone who isn't considered (at least by Buddhists) to be enlightened.
