Once Vyasa came to Pandavas.Vyasa told that he came to know about their plight . So, he came to help them.he taught Prathismruthi,an art to Dharmaraju. Hetold Dharmaraju to teach that art to Arjuna also. With the help of this technique ,arjuna would sharpen his talents hundred fold in all the fields. He would make it happen that Indra ,Siva and other dieties come to him and give their blessed arrows and other important useful tools.they had been longstaying at dvaithavana. He told them to change the place. so,pandavas left for Kaamyayakavana.Dharamaraju taught the art of Prathismruthi to Arjuna. he learnt it and became more powerful. He went to do meditation and thapa and acquire all the powerful armaments . He started to move northern wards and travelled and crossed himalaya gandha maadana mountains, Indrakeelaka mountain.Indra came  and advised him to pray for Siva.

Arjuna went to Himalayas and did great thapa.Siva and Parvathi wanted to test Arjuna. So in the guise of kirathaka couple they went to him.Siva ordered a demon named Mooka, to attack Arjuna in the guise of a pig. Arjuna tried to kill the pig with his gaandeevam. kiratharaju warned him not to kill the animal and he attacked it. The demon disappeared but the controvercy between Kiratha and Arjuna led to a war.they fought tooth and nails . They fought with arrows, swords, and wrestled. But Arjuna could not win over Kiratha and fainted. But Siva was satisfied with the valour displayed by Arjuna.he appeared before Aarjuna in his real state and Arjuna was dumbstruck. He fell over  Sivas feet and praised him.When Siva was pleased and permitted a boon to Arjuna, arjuna asked for Paasupathaasthram and Siva obliged.Comig to know of these developments, Indra and other dikpaalakaas also came to Arjuna. All of them gave their asthraa to Arjuna and vanished.
