I’d say develop your energy, I perform incantations in the astral realm, use the natural creative technologies of the body and consciousness, but you have to do more activating work because you’re charging regions of your body, energy and brain with more prana
What you helps you with developing those channels is up to you, but it takes work
I personally use the zeal chakra a lot and combine words of power with an active mind voice connection, and this connects my state of consciousness to the words, which is the ultimate goal in magick, it’s to shift your state of consciousness to shift into the state that’s already been manifest by your magickal attunemnent
Another thing you want to do is to let go of self, you are not the one casting the magick, the magick is creating itself, you’re just a vessel for that desire to manifest, this is a how people choose their creations, it’s either by unconscious consent or active creation from within. The unconscious intent usually stems from a 3D template of thinking, so you have to increase your dimensional access, and gain more astral knowledge(knowledge that can’t be explained verbally only dimensionally) to access higher dimensional gates, by accessing the light body become the God Consciousness isolated, you deify yourself, and that makes everything mind over matter because your light body is creating all of it, so you become homoluminous, you begin transcending the astral and physical plane with your light, but you have to bathe in this state of consciousness, you have to become it, so you have to meditate as if, to unlock those channels because you always manifest the state you are in
There is no self, so whatever channel you create in your mind slowly attunes you to that state and reality, your body has to catch up.
So in your case, try to feel what it be like if you had that type of power, actualize it in your subconscious by meditating but also practicing, allow your body to integrate it by practicing. Allow all of your to sync up.
Magick is mainly casted by the astral body, so learn to use the technologies available in your light body, train the eye and spirit body.
