Firstly this sub is likely aimed at people closely practicing LOA, energy working, occult (understand by that hidden) sciences, and anything in between that relate to the power of the mind and your extended senses. In my opinion you’re pretty much expected to put the effort alongside using the sub. I do not remotely believe anyone can sit on his ass for 90 days listening to this and expect to drastically improve their skills in the fields I listed above.
If that was true, all these aura-based seduction subliminal would be blatantly working for most of the users by now. You still have to manually work with energy, explore what it feels like and try to control it. To be good at these things, you either get born naturally talented, or work really hard.
To answer your question, what are things you can practically do alongside using the sub…it depends on your goals. What do you expect Alchemist to do for you? What are you goal for exploring the “magick realm” as you said? Some people are just after sheer wonder and fascination, while others strongly believe these stuff can be used as any other tool to improve their life (seduction, money, etc).
So it’ll all depends on that. I recommend you to document yourself.
If you want a general idea of what magick is, what it can and cannot do, there are books about it you can find on Amazon. Like this one, or this other one…and here’s another book, which takes a less traditional approach.
If you have a specific goal like sharpening your extended senses, learning Astral Projection, etc, then gather some solid resources and guidelines you can about that.
Then setup a daily or weekly practice schedule while using the subliminal alongside.
And yes I believe meditation is mandatory. If there’s something loa gurus / yogi / magicians all agree with, it is meditation.
That must be the proper way to use Alchemist.
