It appears that the author of the Prajnāpana Sūtra, Śyāmācārya’s guru Hāstīgotrya "Swāti" is the same as Umaśvāti, the author of the Tattvārthasūtra. These two types of beliefs seem to have been widely popularized later without valid support, as no mention of Umaśvāti as the author of the Tattvārthasūtra or as a disciple of Kundakunda is found in any existent Digambara texts, inscriptions, or the like from before the tenth century. References indicating such connections in Digambara literature, like "Balissahasya Śiṣyaḥ Swātiḥ, Tattvārdhādayo Granthāstu Tatkṛtā Eva Saṃbhavyante," state that his disciple was Śyāmācārya, the author of the Prajñāpana, in Dharma-sāgariya written "Pāṭṭāvali," and inscriptions from Śravaṇa Beḷgoḷa identifying Umaśvāti as the author of Tattvārdha and disciple of Kundakunda are all dated after the eleventh century. See "Jaina Śilālēkha Saṅgraha" [published by Māṇekalāla Pāṇāchanda Granthamālā], article numbers 40, 42, 43, 47, 50, and 108. The "Nandi-saṅgha’s Pāṭṭāvali" is also very incomplete and lacks historical fact; thus, it cannot be relied upon fully. Furthermore, it is not very ancient, as demonstrated by Pāṇḍita Jugalkiśora during his paternal examination. See Swāmī "Samantabhadra" page 114. Therefore, mentions of such connections in that and similar texts cannot be accepted as historical without other established evidence.
