Kumbhaka Paddhati is the only text which deals exhaustively the topic of pranayama. It is extensively quoted by Sunderadeva, another writer on hatha yoga in his Hatha sanketa candrika and Hatha tatva kaumudi. The text describes more than 50 kumbhakas, many of which are not commonly known. Despite the description of various kumbhakas, the author is loud in praise for meru-kumbhaka of which he describes 47 stages. These include all levels of spiritual development.
