Max Freedom Long
In 1917, a year after graduating from Los Angeles State Normal School with an Associate of Arts (two year) degree in General Education, Long moved to the island of Hawaii to teach in elementary schools. When he arrived, he claimed that some Native Hawaiians were practicing what he called magic. Long wrote that at first he was skeptical of this magic, but later became convinced that it worked. He devoted the rest of his life to creating theories about how the Native Hawaiians did what he claimed they did, and teaching those theories through the sale of books and newsletters.
Invention of Huna
Huna Kupua came from the Mana Huna People of early Hawaii. Before present-day Hawaiians, there were the Tahitians. They conqurered and drove into the mountains people known as Menehune, little people or mischievous ones. This is a bastardization of the Mana Huna People. Being that they came down from their hiding places in the mountains at night, stole food from their invaders and cut some of their throats. The Tahitians called us, Menehune. Often the "e" is Hawaiian when used more than once in one word, has a negative context.
Kahili Serge King is the most accurate source of Huna Kupua, and he proves it was not Max Freedom Long that "invented Huna", just like it was not Columbus who discovered America.
The US Bureau of Census shows that there are still 60 of us Menehune or Mana Huna People living on the Island of Kaua'i. And yet, I did not fill out the census forms. Neither did the hundreds of my kin and ohana that are Mana Huna.
Search: Kahili Serge King and/or Huna Kupua to know the facts and the former secrets behind the facts. Most importantly, learn and apply Huna Kupua to liberate yourself from the World Bank and the Military Industrial Establishment along with the heartless archaic priesthood perpetuating all the violence, war and disease in the world.
Long decided to call his compilation of teachings Huna, because one meaning of the word is "hidden secret." He wrote that he derived it from the word kahuna, who were priests and master craftsmen who ranked near the top of the social scale. Long published a series of books on Huna starting in 1936, and founded an organization called the Huna Fellowship in 1945.
Max Freedom Long wrote that he obtained many of his case studies and his ideas about what to look for in kahuna magic from the Director of the Bishop Museum in Honolulu, William Brigham. There is no credible evidence that the two men met. Even if they did, Brigham was not an expert on kahunas and did not document in his own writings any of the incidents Long ascribed to him, including walking on hot lava. In his letters and manuscripts, Brigham stated that Hawaiians were "an inferior race," and implied they were lazy. He referred to Queen Lili'uokalani as a "she devil," "squaw," and "nigger."
Native Hawaiian scholar Charles Kenn, a Living Treasure of Hawai'i recognized in the Hawaiian community as a kahuna and expert in Hawaiian history and traditions, was friendly with Max Freedom Long but said, “While this Huna study is an interesting study, … it is not, and never was Hawaiian.” 
Hawaiian author Pali Jae Lee, a research librarian at the Bishop Museum, conducted extensive research on Max Freedom Long and Huna. She concluded, based on her interviews with Hawaiian elders, "Huna is not Hawaiian." Lee cites Theodore Kelsey, a Living Treasure of Hawai'i renowned for his work as a Hawaiian translator who wrote a letter to Long in 1936 (now in the Hawai'i State Archives) criticizing his use of the terms "unihipili" and "aumakua."
Professor Lisa Kahaleole Hall writes that Huna "bears absolutely no resemblance to any Hawaiian worldview or spiritual practice" and calls it part of the "New Age spiritual industry."
Huna books are "examples of cultural appropriation."
