प्रणवं हीश्वरं विन्द्यात्सर्वस्य हृदये स्थितम् ।सर्वव्यापिनमोंकारं ज्ञात्वा धीरो न शोचति ॥
In plain words
Know Om as the Lord himself, seated in the heart of every being. Having known that Om pervades everything, the steady one does not grieve.
Close to the Sanskrit
One should indeed know the praṇava as the Lord, seated in the heart of all; having known Om as all-pervading, the steady one does not grieve.
