Don’t have much experience with any except for Buddhism. But I’ll give it a go since I’m guessing you aren’t going to get a ton of answers because this isn’t about Noah’s Ark or monkeys or Jesus or whatever…
Kabbalah, besides being a trendy Hollywood scam, is based on Jewish mysticism. If you are into that sort of thing, have fun trying to make sense of it. I highly doubt any of it is based in reality.
Sufism is a mystical form of Islam. Very interesting. I wish I knew more about it.
Buddhism is one of the few religions I respect because it is more psychology than religion. Buddhists do not believe in a god. However, there is a tremendous amount of complex superstition. If you can get through it and make sense of it you should be proud of yourself. I’d recommend a book called ‘The Three Pillars of Zen’ by Suzuki (I think?). Good book.
Gnosticism is a bit tricky. The original Gnostic’s were a ‘cult’ that is associated with the early christians. (But weren’t really.) The basic idea was that if you want to reach the ‘spirit world’ you don’t need a middleman like a priest to get you there. Very complex history.
Hope this was of some help. There are good sources out there on all these subjects and there are very poor New Age sources. You can tell the difference by reading a paragraph in the book and asking ‘How does this person know this is true and how could it be true?’ Trust me, there are a lot of flakes out there.
I just realized I didn’t say anything about yoga. I don’t know much about it but it looks painful.
