अन्तस्तिमिरनाशाय शाब्दबोधो निरर्थकः ।
न नश्यति तमो नाम कृतया दीपवार्तया ॥
antas-timira-nāśāya śābda-bodho nirarthakaḥ |
na naśyati tamo nāma kṛtayā dīpa-vārtayā ||
(Mahāsubhāṣita-saṅgraha: 1661)
“Knowledge of words [i.e., grammar, śāstra] is useless for dispelling inner darkness, as darkness is not dispelled just by engaging in discussion of a lamp.”
