अधीत्य चतुरो वेदान् सर्वशास्त्राण्यनेकश: |
ब्रम्ह्मतत्वं न जानाति दर्वी पाकरसं यथा ||
adhītya caturo vedān sarva-śāstrāṇy anekaśaḥ |
brahma-tattvaṁ na jānāti darvī pāka-rasaṁ yathā ||
(Muktikā Upaniṣad: 2.65)
“[Even] After repeatedly studying the four Vedas and all the śāstras, one does not understand the nature of Brahman, just as a spoon does not know the taste of cooked food [i.e., to realize Brahman one has to not only acquire knowledge of Brahman but also purify the mind of saṁsārika vāsanās].”
