Bhagavad Gita · 18.72

कच्चिदेतच्छ्रुतं पार्थ त्वयैकाग्रेण चेतसा।कच्चिदज्ञानसम्मोहः प्रनष्टस्ते धनञ्जय॥

kachchid etach chhrutaṁ pārtha tvayaikāgreṇa chetasā kachchid ajñāna-saṁmohaḥ pranaṣhṭas te dhanañjaya

O Partha, has this been heard by you with one-pointed mind? O Dhananjaya, has your delusion born of ignorance been destroyed?
