Is becoming a channeler what she was supposed to learn as a take-away message from the channeling we did with her higher self some time ago?

This was implicit in the array of things we could see in her future growth and expansion from continuing on the path she has taken, to become closer to us and to be more and more active as a lightworker in ways that are effective. After all, it is effective lightwork that gets rewarded the most. It does not serve to reward futile endeavors, misguided notions, faulty thinking, and false promises handed down by would-be spiritual teachers who themselves are corrupted. You, yourself, saw the power of the channeling work in reviewing the transcript and saw that, clearly, there is a divine mission underway with her life, and no limits were put on that, nor is it appropriate for you to do so.
