Bhagavad Gita · 2.52

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

yadā te moha-kalilaṁ buddhir vyatitariṣhyati tadā gantāsi nirvedaṁ śhrotavyasya śhrutasya cha

When your intellect crosses beyond the mire of delusion, you will become indifferent to what has been heard and what is yet to be heard.
