ॐ गम्भीरघोषाय विद्महे
गम्भीराय धीमहि
तन्नो रुद्रः प्रचोदयात्
Om Gambhiraghoshaya Vidmahe
Gambhiraya Dhimahi
Tanno Rudrah Prachodayat
Om, may we know Him whose voice resonates like deep thunder,
And meditate deeply upon the unfathomably deep ocean of consciousness;
May Lord Shiva inspire and purify our consciousness.
