योगवासिष्ठः yogavāsiṣṭhaḥ - book-5, chapter-41, verse-14

इदं त्याज्यमिदं ग्राह्यमिति मिथ्या मनोभ्रमः ।
नोन्मत्ततां नयत्यन्तर्ज्ञमज्ञमिव दुर्धियः ॥ १४ ॥

idaṃ tyājyamidaṃ grāhyamiti mithyā manobhramaḥ ,
nonmattatāṃ nayatyantarjñamajñamiva durdhiyaḥ 14

14. idam tyājyam idam grāhyam iti mithyā manobhramaḥ na
unmattatām nayati antaḥ jñam ajñam iva durdhiyaḥ

14. idam tyājyam idam grāhyam iti mithyā manobhramaḥ
antaḥ jñam unmattatām na nayati ajñam durdhiyaḥ iva

14. "This is to be rejected, this is to be accepted"—such a mental delusion is false. It does not drive the truly knowing (jñam) person to madness internally, but it does so for the ignorant (ajñam) and dull-witted.
