To my mind, you have two different things to work on here:
- Skill in clairsenses, which is about getting information through communication with the subconscious, this does not need power.
- The ability to apply energy to change the existing energetic structure in a situation, this is power
You really want both, but clairs is more important imo, as you can still change your actions without using magick to make change, but if you don’t know what’s going on you are working in the dark.
To work on one you want to practice using the clairs, read tarot, build your accuracy with a pendulum try remote viewing, work on lucid dreaming, all that helps
To work on the other you want to practice energy working, like in qigong and build up your person energy stores as well as skill is feeling/reading them, and controlling them.
You’ve probably seen these, but there not there for nothing, what’s needed is diligent practice not a perfect method.
