In this way the issue was mitigated, and the two learned scholars began a long discussion on the Koran and Hindu śāstras. The Lord raised the question of cow-killing, and the Kazi properly answered Him by referring to the Koran. In turn the Kazi also questioned the Lord about cow sacrifice in the Vedas, and the Lord replied that such sacrifice as mentioned in the Vedas is not actually cow-killing. In that sacrifice an old bull or cow was sacrificed for the sake of receiving a fresh younger life by the power of Vedic mantras. But in the Kali-yuga such cow sacrifices are forbidden because there are no qualified brāhmaṇas capable of conducting such a sacrifice. In fact, in Kali-yuga all yajñas (sacrifices) are forbidden because they are useless attempts by foolish men. In Kali-yuga only the saṅkīrtana yajña is recommended for all practical purposes. Speaking in this way, the Lord finally convinced the Kazi, who became the Lord's follower. The Kazi thenceforth declared that no one should hinder the saṅkīrtana movement which was started by the Lord, and the Kazi left this order in his will for the sake of progeny. The Kazi's tomb still exists in the area of Navadvīpa, and Hindu pilgrims go there to show their respects. The Kazi's descendants are residents, and they never objected to saṅkīrtana, even during the Hindu-Muslim riot days.
This incident shows clearly that the Lord was not a so-called timid Vaiṣṇava. A Vaiṣṇava is a fearless devotee of the Lord, and for the right cause he can take any step suitable for the purpose. Arjuna was also a Vaiṣṇava devotee of Lord Kṛṣṇa, and he fought valiantly for the satisfaction of the Lord. Similarly, Vajrāṅgajī, or Hanumān, was also a devotee of Lord Rāma, and he gave lessons to the nondevotee party of Rāvaṇa. The principles of Vaiṣṇavism are to satisfy the Lord by all means. A Vaiṣṇava is by nature a nonviolent, peaceful living being, and he has all the good qualities of God, but when the nondevotee blasphemes the Lord or His devotee, the Vaiṣṇava never tolerates such impudency.
