नादानुसन्धान नमोऽस्तु तुभ्यं त्वां साधनं तत्त्वपदस्य जाने ।भवत्प्रसादात्पवनेन साकं विलीयते विष्णुपदे मनो मे ॥ ४ ॥
In plain words
Listening inward to the sound — I bow to you. You are the way to the ground of what is real; I know this. By your grace my mind melts away with the breath, into the all-pervading.
Close to the Sanskrit
O attending-upon-the-inner-sound, salutation be to you; you I know as the means to the state of Reality. By your grace, together with the breath, my mind dissolves in the abode of Viṣṇu.
