Second Section – the Negative Commandments
168. It is a negative commandment “do not practice sorcery”
As it states in Devarim (Deuteronomy) 18:10, “there shall not be found among yourselves… a sorcerer.” Sorcery is using certain kinds of grasses and stones and combining them with other items people use, and other things like this. A person who does sorcery is liable to the death penalty of stoning. It is forbidden by Rabbinic law for a person to ask for something through sorcery.
This applies in all places and at all times, for men and for women.
4. Be kind to yourself. Speaking badly even about yourself is unethical.
