Translation:
The kings approached Sisupala, who was disturbed like a man who has lost his wife. His complexion was drained of color, his enthusiasm was gone, and his face appeared dried up. The kings spoke to him as follows.
Purport:
Although Sisupala had not married Rukmini, he passionately considered her his property, and thus he was devastated, like a man who has lost his beloved wife.
