Chukim… These are the laws of the Torah that have no reason to them – much like the fact that we are forbidden to eat pork, to mix meat and milk, or forbidden to wear a garment made of Shatnez – a mixture of wool and linen. There’s no reason why these things should be forbidden. Not, at least, according to human logic! However, the Torah is not the mind of a human, it is the instruction book (as well as the Book of Mysteries) given over to us from the Creator of the world – of the universe, and really of everything one could ever imagine to exist.
