Is STS/STO actually about Awareness?

[sillypumpkins]

The only thing I know about Hermetic Law is that it allows things like a YouTube video to do Reiki healing on many people.
I'm sure it's how my Intention Repeater can do things like make you feel stoned and such as well.

I've not found much info on Hermetic Principles though.

The Kybalion is probably the most digestible Hermetic text you can read in the 21st century. I recommend checking it out. It goes over all the principles and more.

The one by Three Initiates?

Yes.

There is also the Corpus Hermeticum which might be of interest as well. It is written in the format of a teacher-student dialogue
