To demonstrate mastery of spoken Pali, one might attempt to clearly articulate the following gem found in DN2. Three times should suffice. This is merely one (1) text segment. How hard can it be?
And for the curious, this was the tongue twister that tied Raveena’s tongue when searching for “kamma”. So don’t search for “kamma” in SuttaCentral Voice until v0.8.0. Well you CAN, but Raveena won’t say anything for you.
By the way…I would welcome any corrections of mispronunciations in that tongue twister–it does have a massive amount of Pali.
