I have been reading the yoga sutras recently and it strikes me how applicable it is. The weird stuff about attaining magical powers is... cool, but samyama and the nature of the reflective consciousness have a lot of explanatory power imo.

Samkhya gives you the Worldview/Model and Patanjala Ashtanga Yoga gives you a practical framework/discipline to implement it. Here is a older comment of mine which you might find useful - https://news.ycombinator.com/item?id=41538322
