Therefore let me surrender unto the Supreme Personality of Godhead and offer my obeisances unto Him, who is beyond the conception of human speculation, the mind, activities, words and arguments, who is the original cause of this cosmic manifestation, by whom the entire cosmos is maintained, and by whom we can conceive of its existence. Let me simply offer my obeisances, for He is beyond my contemplation, speculation and meditation. He is beyond all of my material activities.

अथो यथावन्न वितर्कगोचरं चेतो मनःकर्मवचोभिरञ्जसा । यदाश्रयं येन यतः प्रतीयते सुदुर्विभाव्यं प्रणतास्मि तत्पदम्
atho yathāvanna vitarkagocaraṃ ceto manaḥkarmavacobhirañjasā | yadāśrayaṃ yena yataḥ pratīyate sudurvibhāvyaṃ praṇatāsmi tatpadam
