You watched the last season without watching the previous ones? I can only imagine how strange that must've been for you, hahahaha.

And yes, everything in this material reality can be perceived one way or another, and the interplay between the two perceptions is the energetic core that fuels our existence. Why have one thing or the other when we can have both? Hahaha.

Regarding mystical traditions, you could start exploring Hermeticism with the Kybalion, and also explore Renaissance alchemists such as Paracelsus or Marsilio Ficino. Also, Carl Jung is an excellent source to study, he went deep into these things. When you feel drawn to it, you could eventually include Kabbalah and the Vedas. Have a great exploration!
