I would like to ask a Buddhist question. When the rider of the US Mission delivers the takeaway, he delivers the meat. What kind of cause and effect does he have in it? Does he like eating meat?

No, actually cause and effect is the abbreviation of "cause and effect". How to understand it? We use the process of germination of a seed to understand that if a seed is "cause", then germination is "fruit". From cause to effect, certain conditions are needed, such as soil, temperature, oxygen, nutrients and humidity. Without one, seeds can't germinate, which is called "insufficient karma" and vice versa, so you said this.
