The Subhāṣitaratnanidhi (Sa-skya legs bśad) is a collection of aphorisms by the Sa skya scholar Kun-dga’ rgyal-mtshan dpal bzang-po. Since its publication it has been very popular both in Tibet and abroad. It was subject to an early translation into Mongolian and fragments of it exist in the 'Phags-pa script. James Bosson provides an edition and translation of both the Tibetan and Mongolian texts.
