Prabhupāda: Chand Kazi.
Hayagrīva: Muhammadan.
Prabhupāda: Yes. Muhammadan. Chand Kazi was a... Maulana Chand Kazi. His name is Maulana Chand Kazi. He was a great scholar in the Koran scripture. So Caitanya Mahāprabhu first of all asked the Chand Kazi, "My dear uncle, what is your religion that you are eating your mother and father?" (laughs) So he could understand that He was attacking the cow killing process. So he said, "Well, You are just trying to criticize our cow killing, but in Your Vedic literature also I have seen that cow killing is allowed in sacrifice." Then Lord Caitanya said, "Yes. That is not killing. That is rejuvenating. That is not killing." The sacrifice of cow recommended in the Vedic śāstra means that the brāhmaṇas prove how powerful was Vedic mantra that it could give a new life to the old cows and bulls.
