tad brūhy asaṅgo jaḍavan nigūḍha- vijñāna-vīryo vicarasy apāraḥ /
vacāṃsi yoga-grathitāni sādho na naḥ kṣamante manasāpi bhettum //

18. “Be pleased therefore to answer me. Thou art without attachment; like a dull-witted man, with the concealed glory of superior wisdom, thou goest about in thy infinite greatness, O righteous one. Thy words are couched in yogic style conveying mysterious ideas and are not capable of being solved (understood) even by the mind. [Even those that are endowed with keen intellect cannot see through thy words of yogic knowledge.]
