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.
Pradyumna’s wife, Māyāvatī, could travel in outer space, and therefore they directly reached his father’s capital, Dvārakā, by the airways. They passed above the palace of Lord Kṛṣṇa and came down as a cloud comes down with lightning. The inner section of a palace is known as the antaḥ-pura (private apartments). Pradyumna and Māyāvatī could see many women there, and they set down among them. When the women saw Pradyumna, dressed in yellowish garments, with very long arms, curling hair, beautiful reddish eyes, a smiling face, jewelry and ornaments, they at first could not recognize him as a personality different from Kṛṣṇa. They all felt very bashful at the sudden presence of Kṛṣṇa and wanted to hide in a different corner of the palace.
When the women saw, however, that not all the characteristics of Lord Kṛṣṇa were present in the personality of Pradyumna, out of curiosity they came back to see him and his wife, Māyāvatī. All of them were conjecturing as to who he was, for he was so beautiful. Among the women was Rukmiṇī-devī, who was equally beautiful, with her lotuslike eyes. Seeing Pradyumna, she naturally remembered her own son, and milk began to flow from her breasts out of motherly affection. She then began to wonder, “Who is this beautiful young boy? He appears to be the most beautiful person. Who is the fortunate young woman able to conceive this nice boy in her womb and become his mother? And who is that young woman who has accompanied him? How have they met? Remembering my own son, who was stolen from the maternity home, I can only guess that if he is living somewhere, he might have grown by this time to be like this boy.” Simply by intuition, Rukmiṇī could understand that Pradyumna was her own lost son. She could also observe that Pradyumna resembled Lord Kṛṣṇa in every respect. She was struck with wonder as to how he had acquired all the characteristics of Lord Kṛṣṇa. She therefore began to think more confidently that the boy must be her own grown-up son because she felt so much affection for him, and, as an auspicious sign, her left arm was trembling.
