Mental practice is practice. It always helps, no matter your specialisation.
I know it had benefitted me. No, Damon Brand did not suggest a specific Mental imagery. He said to imagine sharing magic and to not overcomplicate it. After a lot of practice I found one that works for me and also sends the same virtuos signals, that you would like to share magic. I detailed it above; a pulse (of magic) leaving my body. Not absolutely everything will be detailed for you, some things you need to put the work in and find what works best for you. You asked what practices I did and I explained I had practiced during another authors exercise.
That's the danger in blind processes like this.
The early Damon Brand exercises call on the angels of the tablet of nalvage and then the god names of the 4 continents. They are not random.
This comes from the angels themselves and has a long history related to these names. You even use the secret names of God, e.g. pdoce/gaiol.
TBH I don't see "winging it" as "practicing magic
I'm not sure how we got here considering I asked for mentalisation exercises. I simply gave my anecdote (after you asked) of how I grew my concentration, and it happened to come from practicing an excercise from damon brand. If you dont like it, fine. But you asked me.
Additionally, this is enochian language. Please do not say it is winging it. It is a cery sacred language.
But sure, using the sacred god names and tablet of nalvage is rolling chemical dice.
no mental training whatsoever, no groundwork, no nothing, hop right in
Half asked work yields half asked response. He actually asks specific mentalisation for 5 minutes. I couldn't do it at the start. Now I can. Because I read it and re read it and understood the text. I then practiced the exercises. Now I can skip other beginner in the IIH because they were simply doable exercises and move on.
In response to those helping, thank you. Last night during meditation I had strong sensations that I haven't experienced before. I used the "no head excercise". Everything went. That was a new feeling. Held it for about 10-20 seconds. Brain went fuzzy and started making white noise. Went to sleep after as white noise was annoying me.
To summarise; practice is practice. In the same way that working with the magical systems brings magic into your life, meditating begets meditation.
