I'm interested in the safety and efficiency factors of the Daoist path. What if we take the middle ground of doing alone style practice (yes i know everyone says get a master). Unfortunately a lot of people and possibly me included (not sure yet), prefer to practice on our own. So of course even if it is recommended with a master, what sort of safety measures and efficiency paths can we take? It'd be worse for that knowledge not to be spread around knowing that people are going to take a riskier path anyways.
For example, let's say the goal is energy or paranormal work such as healing, astral projection, telekinsesis, etc. What are the prerequsities one should have or take?
