Word for word: 
sūtra-upaniṣadera — of the Vedānta-sūtra and the Upaniṣads; mukhya-artha — the direct meaning; chāḍiyā — giving up; ācārya — Śaṅkarācārya; kalpanā — imagination; kare — does; āgraha kariyā — with great eagerness.
Translation: 
“Giving up the direct meaning of the Vedānta-sūtra and the Upaniṣads, Śaṅkarācārya imagines some other interpretation.
