Bhagavad Gita 2.52
When your reason has crossed the entanglements of illusion, then you will become indifferent to both the philosophies you have heard and those you may yet hear.
यदा ते मोहकलिलं बुद्धिर्व्यतितरिष्यति।
तदा गन्तासि निर्वेदं श्रोतव्यस्य श्रुतस्य च॥yadā te mohakalilaṃ buddhirvyatitariṣyati|
tadā gantāsi nirvedaṃ śrotavyasya śrutasya ca||
