Valmiki Ramayana Kishkindha Kanda Sarga 24 Shloka 18

नृवर O distinguished sire, राघव O Rama, मे in my, हृदि in heart, साधुवृत्तम् good behaviour, इदम् this, अंहः this anxiety, अविषह्य unbearable, अग्नौ in fire, परितप्यमानम् being burnt, विवर्णम् brightens in colour, जातरूपम् gold, किट्टं यथा like the dirt, निवर्तते turned, बत indeed.

'O distinguished Rama this anxiety is unbearable for me. My good behaviour is relegated to the back of my heart unable to bear the sin, just like the dirt surfaces pushing the bright colour of gold when burnt in fire.
