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

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

When thy mind shall escape from this tangle of delusion, then thou shalt rise to indifference as to what has been heard and shall be heard.

In plain words: Krishna says when Arjuna's mind gets free of this confusion, he will no longer care about everything he has heard or will hear from teachings and opinions.
