Lord Siva - Banasura is very dear to me. He has rendered very valuable service unto me; therefore I want to see him always happy. Being pleased with him, I have given him the assurance of safety. I pray to You, my Lord, that as You were pleased upon his forefathers King Prahlada and Bali Maharaja, You will also be pleased with him."
After hearing Lord Siva's prayer, Lord Krsna addressed him also as lord and said, "My dear Lord Siva, I accept your statements, and your desire for Banasura is also accepted by Me. I know that this Banasura is the son of Bali Maharaja, and as such I cannot kill him because that is My promise. I gave a benediction to King Prahlada that all the demons who would appear in his family would never be killed by Me. Therefore, without killing this Banasura, I have simply cut off his arms to deprive him of his false prestige. The large number of soldiers which he was maintaining became a burden on this earth, and I have killed them all in order to minimize the burden. Now he has four remaining arms, and he will remain immortal, without being affected by material the pains and pleasures. I know that he is one of the chief devotees of Your Lordship, so you can now rest assured that henceforward he need have no fear from anything."
