Much of the information about Ushavadata comes from his Nashik and Karle inscriptions. The Nashik inscription contains an eulogy of Ushavadata in Sanskrit, and then records the donation of a cave to Buddhists in a Middle Indo-Aryan language. The Karle inscription contains a similar eulogy, but in the Middle Indo-Aryan language.
[Success !] By permanent charities of Ushavadata, the Shaka, [son of Dinika], son-in-law of king Nahapana, the [Kshahara]ta Kshatrapa....— Inscription No.14a of Nahapana, Cave No.10, Nasik
Both of Ushavadata's inscriptions mention the following of his charitable acts:
- Donated 300,000 cows
- Donated gold for the establishment of a holy site on the banks of the Barnasa river
- Donated 16 villages to the deities and Brahmanas (priests)
- Gave 8 wives to the Brahmanas at the holy site of Prabhasa
- Fed hundreds of thousands of Brahmanas every year
The Nashik inscription records more such acts, stating that Ushavadata exhibited very pious behaviour at the Trirashmi hills, where the Nashik caves are located:
- Donated four-roomed rest houses in Bharukachchha (Bharuch), Dashapura (Mandsaur), Govardhana (near Nashik), and Shurparaka (Nala Sopara)
- Commissioned gardens, tanks, and wells
- Established free crossings at several rivers, including Iba, Parada, Damana, Tapi, Karabena, Dahanuka, and Nava
- Established public water stations on both the banks of these rivers
- Donated 32,000 coconut tree stems at Nanamgola village to the associations of charakas at Pimditakavada, Govardhana, Suvarnamukha, and Shurparaka
- Purchased a field from a Brahmana family, and donated it to Buddhists along with a rock-cut cave (one of the Nasik Caves).
Success! In the year 42, in the month Vesakha, Ushavadata, son of Dinika, son-in-law of king Nahapana, the Kshaharata Kshatrapa, has bestowed this cave on the Samgha generally....— Inscription No.12 of Nahapana, Cave No.10, Nasik
|Nasik Pandavleni Caves, cave No.10|
The Satavahana king Gautamiputra Satakarni appears to have defeated Rishabhadatta. An inscription discovered in Nashik, dated to the 18th year of Gautamiputra's reign, states that he donated a piece of land to Buddhist monks; this land was earlier in the possession of Ushavadata.
