We all know the great power of Mother Nature. When people aligned themselves and their actions according to the laws of the universe, they found magic and support at every turn. Some people have asked, that if the Menehune are so powerful why did they not do anything to stop the destructive changes in their world and why did they not call upon the forces of nature and the universe to rid their world of destructive humans. These incredibly wise beings are walking a path on the mountain that gives them such great vision of our world. They understand with great clarity the potential disruption of interfering with the universe's energy patterns and flow.
Actions can lead to unforeseen and undesired results.
The Menehune would only take action when they could be certain that no harm would come from their actions. And they knew not to try to assess situations without guidance and feedback. The Menehune taught humans about these universal laws. That's why there are so many stories about ancient peoples and their kahuna heeding signs and portents. For example, a kahuna had been called upon to help a family resolve a problem.
