On first consideration, living the intent to 'do no harm' would appear to be simple. Yet when you explore the ramifications of what it means to cause another pain, your entire world view may change. Love others as you love yourself, means first of all that you have to love yourself. Therefore, Huna work begins at home: "Moving into a harmless, hurtless life style we become aware of what we say about our own selves, think about our own selves and feel toward them. We are alerted to other people's speech concerning their own selves. Gradually and painlessly our world view changes." [Enid Hoffman, HUNA: A Beginner's Guide]
Developing an understanding of the thoughts you take in as "food" is particularly necessary. The low self (unconscious mind) is particularly literal in its translation of sensory input. If you constantly live in a state of anxiety about the conditions of your life, you are sending this message to low self, and self-defeating responses are developed. Low self looks to middle self for guidance. If you tell low self all is hopeless, low self believes you. If you would create improved conditions you must first understand your own personal self-talk and mediate the messages you send to low self. Secondarily, take a look at all intimate relationships. If you have been expecting less from these, rather than more, change your self-talk in this respect.
Of equal importance, and often affecting self-talk, is a media culture that reflects debasing attitudes toward the unconscious. Observe how media approaches all issues surrounding psychic functioning. The prevailing attitude of guarded interest is either wrapped in giggles, incredulity, or - in most fiction - as dangerous, mind-warping, or - in religion - connected to powers of darkness and evil, or conversely to positive manifestations like guardian angels. This cultural slant negates the proper functioning of low self. Accepting a cultural bias that flirts with the thrill of psychic phenomena, while at core fearing it, is ludicrous. Knowledge is diminished by minimalist treatment of the subject. Thus in the end we are left with attributions that neither describe or discriminate the various phenomena. The river becomes dark, dangerous, and evil - a place where no sane man would swim. By accepting such cultural biases, we cut ourselves off from what Ingo Swann calls the "superpowers of the biomind".
The Kahuna concepts place a great deal of emphasis upon accumulation and allocation of mana/prana/chi (pick a word). The development of will and clarity of intent are the secondary emphasis arising from the first. The third and foremost emphasis is the development of an attitude of service that assist, without harming, others. When you begin to wrestle with this one you discover how fine the line is between self-interest and altruistic helpfulness, and the importance of your relationship to yourself.
I have studied remote viewing with Paul H. Smith for 7 years. My practice of the Kahuna concepts began more than 20 years earlier. Recently I have listened to many conversations regarding issues surrounding the development of remote influencing. Contamination of the concept of 'remote healing' has occurred with the advent of the term 'remote influencing'. Basically they are the same thing only directed to different purposes. However, I think as research proceeds it will be discovered that the individual potential to negatively influence another person is highly overrated (mostly by over-dramatization in movies and a cultural trending toward magical thinking). According to Kahuna concepts, underlying all our mental hard-wiring is a protective feature - High Self - that disallows the external tinkering and effectiveness of negative psychic input -- only that which we accept becomes part of us. Additionally, once the underlying dynamics that affect the outcome of remote influencing are understood, it is unlikely that any intelligent practitioner will do less than adhere to the "no hurt, no harm to anyone" code of ethical practice. He who is unaware of the boomarang effect will be abruptly awakened.
Success stories of personal and others healings abound in the Huna work; I have my own. But, until you experience the actuality yourself, stories are just stories. So I would urge you to gather some information and begin to practice. Just as is true in remote viewing, it's all about the clarity of communication developed among the selves within your self. It's about "talking to self". As with Controlled Remote Viewing it requires dedication, an understanding of the structure, and practice; it also - like CRV - is life enhancing and only harmful to those who would abuse power.
The attitude of the kahuna practitioner is similar to that of the Senoi, in that both cultures attend to the importance of thought forms as well as actions. It is expected that one will make amends for harmful thought and action, and strive to ferret out the negative before the roots grow too deeply. If we indeed expect to evolve into a culture of any psychic depth, it becomes a necessity that we strive to develop a code of doing no harm on All levels of expression. From the kahuna perspective we are already an intimately connected and psychically communicating species: some of us just don't know it yet.
