Do the processes yourself as a practice
Having personal experience with how the method works is essential. This lays the foundation for being able to effectively guide someone else, and to teach the work congruently. The longer you have done this practice yourself, the more you will have intuitions to draw upon when guiding someone else.
There isn’t a set number of days to do this practice that is suddenly “enough,” although I encourage doing the personal practice for three months (90 days) before beginning to teach in a significant way.
Note: it can be extremely helpful to work with the impetus to teach, as part of the inner work we each do. Is there a “one who” is really excited to teach? Is there a “one who” is so excited and wants to begin immediately? These are wonderful impulses. And we personally, plus our teaching, will benefit from integrating this impulse. In the advanced training days, you learn more options for how to fully integrate this.
