As I understand it, there’s two aspects of the work here:
- Improving the communication with your subconscious, which is the part of you that is aware and gets all the AP type information and has to pass it along to your conscious mind.
- Raising your energy levels which in turn will strengthen your spirit, which also improves (1).
It is possible for spirits to give you a boost and adjust your energy levels for you. It’s rare but does happen.
By using sigils etc you are setting your focus and intention that you want to raise your skills, and that helps already. Energy follows mind.
You don’t say what kind of meditation you do, but to make headway on the communication and energy levels, you probably want to use techniques designed to do that.
For communication, this is about listening yo your intuition, which is your subconscious talking to you, and giving it more changes to be heard. The more you listen to it and practice he better that gets. Using pendulums, muscle testing, tarot cards, and learning remove viewing do this directly.
For energy raising, I like qi cultivation, but there’s also pranic breathing, and the wim hoff method, probably others I don’t know about.
