“We cannot even ascertain which caste this Kṛṣṇa belongs to or what His actual occupational duty is.” Actually, Kṛṣṇa does not belong to any caste, nor does He have to perform any occupational duty. It is stated in the Vedas that the Supreme Lord has nothing to do as His prescribed duty. Whatever has to be done on His behalf is executed by His different energies.
Śiśupāla continued: “Kṛṣṇa does not belong to a high family. He is so independent that no one knows His principles of religious life. Indeed, it appears that He is outside the jurisdiction of all religious principles. He always acts independently, not caring for the Vedic injunctions and regulative principles. Therefore He is devoid of all good qualities.” Śiśupāla indirectly praised Kṛṣṇa by saying that He is not within the jurisdiction of Vedic injunctions. This is true because He is the Supreme Personality of Godhead. That He has “no good qualities” (guṇaiḥ hīnaḥ) means that Kṛṣṇa has no material qualities, and because He is the Supreme Personality of Godhead, He acts independently, not caring for conventions in social or religious principles.
Śiśupāla continued: “Under these circumstances, how can He be fit to accept the first worship in the sacrifice? Kṛṣṇa is so foolish that He has left Mathurā, which is inhabited by highly elevated persons following the Vedic culture, and has taken shelter in the ocean, where there is not even talk of the Vedas. Instead of living openly, He has constructed a fort within the water and is living in a place where there is no discussion of Vedic knowledge. And whenever He comes out of the fort, He simply harasses the citizens like a dacoit, thief or rogue.”
Śiśupāla went crazy because of Kṛṣṇa’s being elected the supreme, first-worshiped person in that meeting, and he spoke so irresponsibly that it appeared he had lost all his good fortune. Being overcast with misfortune, Śiśupāla continued to insult Kṛṣṇa, and Lord Kṛṣṇa patiently heard him without protest. Just as a lion does not care when a flock of jackals howl, Lord Kṛṣṇa remained silent and unprovoked. Kṛṣṇa did not reply to even a single accusation made by Śiśupāla, but all the members present in the meeting, except for a few who agreed with Śiśupāla, were very much agitated because it is the duty of any respectable person not to tolerate blasphemy against God or His devotee. Some of them, who thought that they could not properly take action against Śiśupāla, left the assembly in protest, covering their ears with their hands in order not to hear further accusations. Thus they left the meeting, condemning the action of Śiśupāla. It is the Vedic injunction that whenever there is blasphemy of the Supreme Personality of Godhead, one must immediately leave. If he does not do so, he becomes bereft of his pious activities and is degraded to a lower condition of life.
All the kings present, belonging to the Kuru dynasty, Matsya dynasty, Kekaya dynasty and Sṛñjaya dynasty, were very angry and immediately took up their swords and shields to kill Śiśupāla, who was so foolish that he was not even slightly agitated, although all the kings present were ready to kill him. Śiśupāla did not care to think of the pros and cons of his foolish talking, and instead of stopping when he saw that all the kings were ready to kill him, he stood to fight with them and took up his sword and shield. When Lord Kṛṣṇa saw that they were going to fight in the arena of the auspicious Rājasūya-yajña, He personally pacified them. Out of His causeless mercy He Himself decided to kill Śiśupāla. When Śiśupāla was abusing the kings who were about to attack him, Lord Kṛṣṇa took up His disc, as sharp as the blade of a razor, and immediately separated Śiśupāla’s head from his body.
