A week or two ago I also thought about making a post asking about magick
and spirits to work with for bending time.
But from my perspective it was more about the powers that can make you progress faster towards goals.
From what I saw most commonly Angels are worked with to achieve this, a very common one is Metatron,
who is supposed to have some dominion over time and space.
There are many others, also mostly specific to the tasks and things one wants to achieve.
Also working with planetary powers, hence also the pagan pantheons make sense here,
as they usually inherit some form of personification of a universal cosmic law that
one wants to nudge into the favored direction.
Maybe Mercury for learning languages, Mars for competitive situations etc.
That's how I would approach magick for bending time.
Maybe you could work with different spirits to ease your trauma, doing some physical release exercises-
and as many here said before- talk to people, professional help is the best way not to burden personal relationships
with the weight of topics that may trigger both sides, or even if a good friend is listening- it may put pressure on the relationship.
That's why counseling or helplines exist.
And I wanted to add one thing about the mentioned book 'Unleash extreme occult power':
Not to mock anybody, you can draw useful things out of the most unusual places, but it smells like moneygrab to me.
There are many occult publishers that are on the 'artificial-scarcity-track', but some at least have the dignity to make up for some things in production quality. I think there are many places to learn about the siddhis and other powers cheaper or even for free.
Especially in buddhist and vedic/tantric teachings.
