It is of course important to learn basic techniques like energetic manipulation, chakra control, raising energy, grounding, cycling energy, draining energy, sending energy, etc etc etc. People who are attempting to astral project should consider these abilities to be basic building blocks. Astral projection is not calling the corners or burning sage, it is a mid level technique that ought to only be utilized by those who have mastered the basics. Namaste▲
