I have been asked about a healer who claims her protocol is more effective in clearing karma because she uses code words and says this is much more efficient than clearing karma using the Lightworker Healing Protocol, as the latter needs one-to-one sessions that are too time-consuming. Is she correct?

She is not correct as she is misunderstanding things with both her declarations here. First, that her codes are all-important to healing karma and, the second, that the LHP is so powerless in comparison. Neither are correct. If anything, the reverse is the case, that the LHP is complete and therefore superior in what it can do, whereas her approach has limitations, energetically, despite her strong belief to the opposite. So she is misleading both herself and her followers to make such pronouncements. That is most unfortunate because it will also have karmic consequences for her in guiding people away from the best answer for their issues to benefit herself. The mitigating factor is that she does mean well, but she must, nevertheless, take responsibility for all she does and does not do, and that will be seen clearly by the Law of Karma and acted upon always.
