Shauca is one of the five niyama's. According to Patañjali shaucaat svaan.ga-jugupsaa parair asaMsargaH.
Taimni's translation: >From physical purity (arises) disgust for one's own body and disinclination to come in physical contact with others. Have you ever noticed this disgust for your own body, full of shit and urine, etc? BTW, that'a an nice example of the importance of indicating the long vowels in Sanskrit, in this case the long a-sound (aa, a: , a_ , A , etc.), namely: svaan.ga with a long a-sound in the middle is sandhi for sva + an.ga: svAGga n. a limb of oñone's own body , oñone's own bñbody , limb or body in the strict (not metaphorical) sense Ka1v. Yogas. &c. ; whereas svan.ga with a short a is sandhi for su + an.ga svaGga mfn. having a beautiful body , well-shaped , fair-limbed RV. ; n. a good or handsome limb MW.
