The relic casket, carved from steatite, once enshrined the sacred relics of Bhagwan Buddha, the Enlightened One. An inscription in early Brāhmī script adorns its surface, reading: “Sukiti-bhatinaṁ sabhagiṇikanaṁ sa-putadalanaṁ iyaṁ salila-nidhane Budhasa bhagavate sakiyanaṁ,” which translates as “This is a deposit of the relics of the Buddha, the august one, by the Śākyas, the brethren of the distinguished one, in association with their sisters, children, and wives.” The inscription attests to the Śākya clan’s reverent veneration of the master.
