I haven’t mastered the teachings in 7-week course yet. Should I focus on integrating those before jumping into Mastery?

Absolutely not. You don’t need to have mastered everything you learned in the 7-week course. The Mastery program is designed to guide you, from beginning to end, in the process of mastering Feminine Power precisely because we know that that cannot be done in 7 weeks! We went through the material very quickly in the 7-week course, and during Mastery we really slow things down and go much deeper.
