एकः शब्दः सम्यग्ज्ञातः शास्त्रान्वितः ।
सुप्रयुक्तः स्वर्गे लोके कामधुग्भवति ॥
ekaḥ śabdaḥ samyag jñātaḥ śāstrānvitaḥ |
suprayuktaḥ svarge loke kāmadhug bhavati ||
(Mahābhāṣya: 6.1.84; cited in Sāhitya-darpaṇa 1.2)
“[Even] One word fully understood, in conformity to [grammatical] rule, and properly used, becomes a wish-fulfilling cow in Svarga and in this world.”
