One of the best channels I've found on YouTube for people who want to delve into these matters is Liquor of Wisdom, run by a Romanian practitioner of superb knowledge and a stupendous way of explaining all of these topics. She can also point you to important literature on them, although if it's about bibliographical sources, a great channel you can check is Foolish Fish, whose videos are all about books and research.
Regarding Hermetic Tradition, the best you can do is find the Kybalion and start there. Regarding Kabbalah, there's a wonderful series where an American rabbi explains the topic really well. This is the first video. As for the Vedas, @julescape is the best source I know on the platform for that topic in particular. He can tell you a lot more about that than I could.
Awesome. Thank you very much! <3
