Kumbhaka Paddhati is the only text dealing exclusively on 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 menu-kumbhakas, the author praises Meru Kumbhaka of which he describes 47 stages. These include all levels of spiritual development. These stages are a continuum of experiences the yogi passes through as a result of continuous practice of kumbhakas. These are not described in the available texts. Therefore, it is the unique feature of Kumbhaka-Paddhati.
