sthana forPitta175 and Chakrapani comments that Pittasthana denotes
Amasaya.Amasaya:Amasaya is one of the koshtangas, situated in between nabhi and
sthana176.Its involvement in the causation of swasa can be enunciated based on the
followingpoints: Amasaya is the moola for Anna vaha srotases, which is primarily

uras, sosha of which occurs by the effect of swasa188.SROTASES: ‘Srotas’ denotes a
channel, and the entire body is composed of innumerablesrotases which are classified
into Antarmukha and Bahirmukha. Though Antarmukhasrotases are innumerable,
