This document is designed to be used with Light on Prāṇāyāma open alongside it. It is not a substitute for the book and does not reproduce its instructions. What it offers is a map of the book’s argument: how Iyengar’s teaching on pūraka, recaka, and kumbhaka develops across thirty chapters, what his metaphors are doing, where the techniques fit, and where the text leaves questions open.

Part I explains how the document is organised and how to navigate it. Readers who prefer to start elsewhere can go directly to whichever section serves them now and return to Part I when needed.

All citations are to the standard English edition. Chapter and paragraph numbers are used throughout.
