I can give you an example if you like…if you read ummagga jathaka…(will say in simple) there is a verse call “ikbithi mahawshadha pandithayo pawuru bamme katu kohol shuddha karawa” etc… that means remove all other than wall….in that sence it means removing all….also make it clean like...ok...in...
nope....i check with litreture...its a double meaning word man sudda kiyana wachane, sudda (white man) kiyana eken, un karapu winashayen bindichcha ekak , niyama sinhala wachane, shudda....both for pure and distroying....
