parāśara uvāca:
tataḥ praṇamya muditaḥ śambhum abhyāgato gṛham
bhagnaṃ ca dhvajam ālokya hṛṣṭo harṣāntaraṃ yayau //

BEFORE this took place, Báńa had been engaged in the adoration of the three-eyed god, and had thus prayed to him: "I am humiliated, O lord, by the possession of a thousand arms in a state of peace; let some hostilities ensue, in which I may derive some advantage from their possession. Without war, what is the use of these arms? they are but a burden to me." Śankara replied, "When thy peacock banner shall be broken, thou shalt have war, the delight of the evil spirits that feast on the flesh of man." Báńa, pleased by this promise, proffered his thanks to Śambhu, and returned to his palace, where he found his standard broken; at which his joy was increased.
