In this session, we found ourselves asking a question that sounds almost too simple: why does one prāṇāyāma have twice as many stages as its apparent mirror image? Anuloma and Pratiloma look like two sides of the same coin — one controls the exhalation with the fingers, the other controls the inhalation. So why does Anuloma have 16 stages while Pratiloma has only 8? We sat with the tables and looked for what was missing, and the answer was hiding in plain sight at the end of Chapter 26, in a note most readers glide past. Iyengar explains that combining interrupted breathing with the already-demanding inhalation control of Pratiloma would cause undue strain and damage the very sensitivity the practice is designed to cultivate. The answer was in the text all along — the right question just had to arise first.

We also untangled a paradox sitting at the heart of these chapters. Iyengar tells us never to practice Sūrya Bhedana and Chandra Bhedana on the same day — one heats the system, the other cools it, and doing both is like pushing the nervous system to one extreme and then yanking it to the other. And yet Nāḍī Śodhana, the final and most advanced prāṇāyāma in the book, does exactly that: it integrates inhalation through the right and inhalation through the left into a single rhythmic cycle. The difference, we realized, is that Nāḍī Śodhana holds both energies in continuous balance rather than maximizing one. It is not the combination of Sūrya and Chandra Bhedana — it is their resolution. Iyengar writes that when this practice is refined to its subtlest level, it takes the practitioner to the innermost self. That is why he calls it the most difficult, complex, and refined of all prāṇāyāmas.
