Bhagavad Gita: Chapter 2, Verse 52

यदा ते मोहकलिलं बुद्धिर्व्यतितरिष्यति ।
तदा गन्तासि निर्वेदं श्रोतव्यस्य श्रुतस्य च ॥ २-५२ ॥

yadā te moha-kalilaṁ buddhir vyatitariṣyati
tadā gantāsi nirvedaṁ śrotavyasya śrutasya ca 2.52

When your intellect crosses the dense forest of delusion, you shall become indifferent to all that has been heard and all that is to be heard.
