Each of us gets training, either from someone they trust, reading about the life, or from the net. I was lucky enough to be discovered by a great Dom and Mentor. I met his mentors and socially other members of the society.
Even in the society I did not accept all they taught, like most of us I took what I needed and made sense to me. Today I am still learning that is a major reason for being here.
Please don't take that statement as a brag it is not. The society also had devil worshipers in it and I took none of their training.
