PURPORT

Lord Siva tested Arjuna's strength by picking a quarrel with him over a hunted boar. He confronted Arjuna in the false dress of a hunter, and Arjuna covered him with arrows until Lord Siva was satisfied with Arjuna's fighting. He offered Arjuna the Pasupati weapon and blessed him. Here Vidura inquired about the great warrior's well-being.
