काष्ठपाषाणधातूनां कृत्वा भावेन सेवनम् ।
श्रद्धया च तथा सिद्धिस्तस्य विष्णुप्रसादतः ॥
kāṣṭha-pāṣāṇa-dhātūnāṁ kṛtvā bhāvena sevanam |
śraddhayā ca tathā siddhis tasya viṣṇu-prasādataḥ ||
(Cāṇakya-nīti-darpaṇa: 8.12)
“If one serves that which is made of wood, stone, or metal [i.e., a deity] with bhāva and śraddhā, then siddhi [i.e., success in one’s worship] occurs by Viṣṇu’s grace.”
