People do ascribe mystical, religious, metaphysical constructs to practises of meditation. These may not come in the same language as a computer instruction manual. But the practise of mental withdrawal required to get to a state of observation is similarly assisted by following step by step mental excercises; ones that assist concentration. They are technical, repetitive, and enhance focus. Just as someone working with a computer needs to follow certain steps to get an outcome, so a yogi needs to go through a process of complex mental excercises to achieve a state of withdrawal.

Discussions afterwards about what happened and ascribing some moral epiphany or heightened benevolence are the subjective mind interpreting the after effects according to a local cultural phoilosophical context and expectation.

But someone in another era describing a car, a plane, or an operation may resort to mystical language too, because they can't possibly understand it.

That said, it's amazing.
