Māyāvatī had mystic knowledge of supernatural powers. Supernatural powers are generally known as māyā, and to surpass all such powers there is another supernatural power, called mahā-māyā. Māyāvatī had the knowledge of the mystic power of mahā-māyā, and she delivered to Pradyumna this specific energetic power in order to defeat the mystic powers of the Śambara demon. Thus being empowered by his wife, Pradyumna immediately went before Śambara and challenged him to fight. Pradyumna addressed him in very strong language, so that his temper would be agitated and he would be moved to fight. At Pradyumna's words, the demon Śambara, being insulted, felt just as a snake feels after being struck by someone's foot. A serpent cannot tolerate being kicked by another animal or by a man, and it immediately bites its opponent.
Śambara felt the words of Pradyumna as if they were a kick. He immediately took his club in his hand and appeared before Pradyumna to fight. Roaring like a thundering cloud, in great anger the demon began to beat Pradyumna with his club, just as a thunderbolt beats a mountain. Pradyumna protected himself with his own club and eventually struck the demon very severely. In this way, the fighting between Śambarāsura and Pradyumna began in earnest.
But Śambarāsura knew the art of mystic powers and could raise himself into the sky and fight from outer space. There is a demon of the name Maya, and Śambarāsura had learned many mystic powers from him. He thus raised himself high into the sky and threw various types of nuclear weapons at the body of Pradyumna. To combat the mystic powers of Śambarāsura, Pradyumna invoked another mystic power, known as mahāvidyā, which was different from the black mystic power. The mahāvidyā mystic power is based on the quality of goodness. Śambara, understanding that his enemy was formidable, took assistance from various kinds of demoniac mystic powers belonging to the Guhyakas, the Gandharvas, the Piśācas, the snakes and the Rākṣasas. But although the demon exhibited his mystic powers and took shelter of supernatural strength, Pradyumna was able to counteract his strength and powers by the superior power of mahāvidyā. When Śambarāsura was defeated in every respect, Pradyumna took his sharp sword and immediately cut off the demon's head, which was decorated with a helmet and valuable jewels. When Pradyumna thus killed the demon, all the demigods in the higher planetary systems showered flowers on him.
