Kauśikaprajñāpāramitāsutra contains many Prajñaparamita mantras which include: oṃ hrī śrī dhī śruti smṛti mati gati vijaye svāhā [ninety two] , that may be interpreted as “the internal hearth that burns absent impurities and poor karma.” At some time, Malia states, she didn't entirely realize the this means on the mantra. https://reidvmbob.shoutmyblog.com/26341988/fascination-about-mantra
