The Works of Vācaka Umāsvāti 3
(1)
The Saucaprakaraṇa
Gandhahasti Siddhasena Gaṇī, in his commentary (C. AD 760-70) on the Sabhāṣya-Tattvārthādhigama-sūtra (c. AD 350), thus quotes from Umāsvāti's Śaucaprakaraṇa:10
Tathā tasyaiva bhāṣyakṛtaḥ Śaucaprakarana granthaḥ:
Adattādānaṁ nāma paraiḥ parigṛhitasya tṛṇāder-apyanisṛṣasya grahanam steyam/
In this context, a notice taken by Muni Śīlacandravijaya (now Acārya Vijayaśīlacandra Suri), of a quotation figuring inside the commentary (probably before AD 1025) of Vadivetāla Santi Sūri (of the abbatial order Thārāpadra-gaccha) on the Uttarādhyayana-sūtra 12.39 ('Harikeśi-adhyayana') in the name of 'Vācaka', may also be considered:11
Tathā ca Vācakaḥ:
Śaucam-ādhyātmikaṁ tyaktvā bhāva-śuddhy-ātmakaṁ śubhaṁ/ jalādi-śaucam yatreṣam mūḍha-vismāpakaṁ hi tat/
This verse advocates preference for the spiritual/internal cleanliness (sauca) to the one externally done (of the body through the use of) water, etc. To all seeming, this verse, too, had belonged to the above-noted lost Śaucaprakarana and the 'Vācaka', whose authority is here invoked, predictably is none else but Umāsvāti, an inference that as well receives support on the basis of the stylistic features of the verse under reference.

The Śrāvakaprajñapti
Some Svetambara writers of our time confounded (and still confuse) the Savayapanṇatti, a prakarana in Prakrit by Yakinīsūnu Haribhadra Sūri (of Vidyadhara Kula) (c. 3rd quarter of the eighth century AD) with Umāsväti's Śrāvakaprajñapti. 12 The last-noted work, to all seeming, had been composed in Sanskrit,
