magic requires self-actualization, self-realization, and knowledge of the fundamentals of the universe in order to work. Even then, it requires esoteric knowledge, unless you have a natural affinity.
In order to actually cast a spell or perform a ritual you need to enter into a mental state where your perception of self and perception of the world are merged. Kind of hard to describe how it feels, but basically you will begin to visualize objects and most importantly your own body, as being larger, closer, farther, clearer, or all of the above. This can bring discomfort to a lot of people, but if you train yourself to endure it you can actually use magic.

When I enter into this state, my perception of my own body rapidly changes. I'm unable to focus on my external senses, or rather I'm not aware of them. It almost feels like my brain is 'pulsing'. My hands feel larger than normal, I feel like I'm swaying back and forth or spinning, and when I start reciting my mantra (a necessary step to keep yourself from having a psychological break) all of my perception is suddenly forced onto my lips and tongue as they move.

If you're not careful, you can damage your mental state doing this. Magic is risky to use. Humans weren't meant to access this power. We're mentally blocked to keep ourselves from going insane. A lot of people think that the most powerful people in the world are Archons who can use magic to influence probability. Can't say I disagree. Rothschilds are insanely powerful individuals, but they are also incredibly mysterious.

This is useful. Thank you for the description, it was very good information. 

I've attained such states through shrooms, Wim Hof meditation and other methods.

Sounds legit to enter that state to do magick.

Some members of a group I'm part of have experimented with dosing boiled Amanita Muscaria mushrooms in order to more easily enter into the mantra state but I recommend against it since you lack the clarity of mind required to maintain your sanity in the long term. This is pretty much only used to enter vision quests or divining universal secrets since you can't really recite incantations while you're stoned out of your head.

Thats true, another problem could be dependence.

I think is good to try that a couple of times to 'know' whats there, but one should learn to be capable of rely on its own non-altered mind, that's how we have to deal with everyday life at the end of the day.
