There is a vow of not stealing, asteya. There is a vow of chastity. Now of course a regular practitioner is going to be able to have a sexual life but not be a slave to sexual passion. And of course monks and nuns are going to take a vow of celibacy. They're not going to go anywhere near that, how about that. And then the last vow is non-possessiveness, that we need to live a life where we are not attached to matter, to objects. That our goal is to live a life where we remove karma and free our souls of this repetitive pattern of reincarnation so we can achieve moksha.
