Hi, there are many goods posts and whole threads here that will help. I recommend spending some time gleaming them.
I agree whole-heartedly that to shift from outer to inner mind dominion can be daunting. However, many have done it!
But sadly most fail.
So, you do need to want to do this very badly, mastery comes with the price, attention.
I would recommend this stated method right at the start:
Photoread the books upside down and from the back page forward to the front matter of the book.
Sing your affirmations out loud while you do this to better distract your sub-vocalizing mind.
Kind regards,
