In plain words
Partha’s heart was full of pity. His sorrow swelled and tears overflowed his eyes. Seeing him grieving so, and so that his grief might leave him, Madhusudana spoke these words, setting them out in order.
Word for word
Seeing that Partha, whose heart was full of compassion, grieving as sorrow and tears increased, Madhusudana spoke these words distinctly so that his sorrow might depart.
