त्वम् you, गदाधरम् holding a mace, इह here, तिष्ठन्तम् while standing, धातुभिः with minerals, चितम् inlaid, पर्वतम् mountain, धराधरमिव like supporter of earth, अकम्प्यम् unshakeable, माम् me, पश्यसि you are seeing, ननु indeed.
Indeed, (it is strange that) you do not see me holding a mace and standing here like an unshakeable mountain which contains minerals and supports the earth.
