You know… you have to let yourself get possessed by the energy of the thing for it to be truly potent.
Let it work through you, so to speak - take a back seat.
Meditation, fasting, spiritual learning, compassion, etc. All of this things will help you hear the whispers of the upper realms more easily.
You want confidence? experience what it’s like to be a tiger or a lion, and then, if your brain waves are low enough - conceptualize pulling the thing and anchoring it into the image or audio - or whatever.
It’s really simple, and if you’re in-tune enough - some things will even call to you, like the time with Phanuel, Splendor Solis, Potion of the 3 Magi, etc. (for me it was a buzzing in the ear that I had to meditate on and execute)
That’s as far as energy goes.
Morphic Fields are more like backward engineering something - so they require studying and analysis - a lot of information gathering goes into it - it has to have a quantum subfield of support to work.
So you can’t make a morphic field for “Confidence” per se - it has to be a chemical like Androstadienone or Androstenol with a deep understanding of what they bind to and what they release. You’ll have to have a lot of data and leave no loop holes - and you will also be exploring that space to see if there is any information that you’ve missed. It is a lot more detailed than energetic programming - as the latter is far more intuitive, while the former is significantly more “taxing” and “time-consuming”.
The core principles are the same, but there’s a huge divergence in execution.
I’d like to learn as well
And I am not saying this about Intention Repeater’s creator specifically (I don’t know this person), but those who get it, get it.
