Lord Buddha appeared, all kinds of sacrifices would be stopped, and thus their husbands would not be invited to such ceremonies and would not be separated from them.
Sometimes it is inquired, "Why don't the demigods from higher planetary systems come to this earth planet nowadays?" The plain answer is that since Lord Buddha appeared and began to deprecate the performance of sacrifice in order to stop animal-killing on this planet, the process of offering sacrifices has been stopped, and the demigods do not care to come here anymore.
