I actually came across The Black Sun because I was looking into Qigong (you’ve mentioned it several times, so I started digging into it in comparison with Vedic medicine/healing practices). The doshas appear similar to the qigong eight energetic principles and how an excess of different emotional energies effect the function of different organs. I’ve just been casually reading about it though, the concepts are intriguing and have real world applications (especially in reframing our understanding of how we may may think our physical bodies operate).
