Translation:

After the King’s son Sudakṣiṇa had performed the obligatory funeral rituals for his father, he resolved within his mind: “Only by killing my father’s murderer can I avenge his death.” Thus the charitable Sudakṣiṇa, together with his priests, began worshiping Lord Maheśvara with great attention.

Purport:

Śrīla Prabhupāda writes: “The lord of the kingdom of Kāśi is Viśvanātha (Lord Śiva). The temple of Lord Viśvanātha is still existing in Vārāṇasī, and many thousands of pilgrims still gather daily in that temple.”
