the translation of their texts is widely available, I started with tibetan yoga and secret doctrines by evan-wentz. There’s a lot of lore and tradition you need to understand for some of it but the gist is there.
But… Does it become better after leaving academia? I am just done with my PhD and will leave for industry in 1 month. Even having finished my PhD, I can’t see light at the end of the tunnel. Suggestions?
