The parallel from the Udānavarga of Subashi, edited by Nakatani, has “yadā svakevu dharmeṣu” on your site, but “yadā svakeṣu dharmmeṣu” in Nakatani’s scanned PDF. I believe your variant is due to an OCR error, so I thought I’d point it out in case you want to correct it.
@Aminah - just tagging you in here. Indeed, the Udanavarga de Subashi was one of my pet projects and it turned out very difficult to get the OCR right and check the whole thing, most of which Aminah did!
