Astanga Hrudaya
बिसानामिव सूक्ष्माणि दूरं प्रविसृतानि च। द्वाराणि स्रोतसां देहे रसो यैरुपचीयते॥४६॥
Simily for nourishment of the body by channels: Just like the minute orifices of the lotus stem are spread out throughout the stem, the openings of the srotas i.e. channels (are also spread out throughout the body), (through these orifices) the body gets nourished by the the rasa (i.e. the nutritive juice derived after the food gets digested in the stomach).
