मम पश्यतः within my very sight, त्वम् you, वैदेहीम् Vaidehi, न्यायसंसिद्धैः by those bound by logic, हेतुभिः by reason, ध्रुवाम् everlasting, वेदश्रुतीमिव like revelations of the Vedas, बलात् by force, हर्तुम् abduct, न शक्तः not possible for you.
You cannot carry Vaidehi by force within my very sight just as the everlasting revelations of the Vedas cannot be robbed by mere logic of reason.
