Huna is a Hawaiian term for “Secret”. But its practical application makes it a universal method for growth and achievement.
The 7 fundamental principles of Huna are:
IKE – The world is what you think it is KALA – There are no limits, everything is possible MAKIA – Energy flows where attention goes MANAWA – Now is the moment of power ALOHA – To love is to be happy with MANA – All power comes from within PONO – Effectiveness is the measure of truth
Note: Some say Huna is a New Age, not Hawaiian concept. Nevertheless, I am in general agreement with the principles above.

From Knowing to Awareness 
The transformative imperative challenges conventional beliefs about the nature of reality. Unlock and unblock your natural abilities. We take our world to be an objective reality, but is it? The assumption that the physical world exists in and of itself has struggled to assimilate the findings of modern physics for some time now. For example, an objective space and time would just "be", but in relativity, space contracts and time dilates. Likewise objective "things" should just inherently exist, but the entities of quantum theory are 'probability of existence' smears, that spread, tunnel, superpose and entangle in physically impossible ways.
Cosmology tells us that our entire physical universe just "popped up", from nowhere, about 14 billion years ago. This is not how an objectively real world should behave! We are therefore forced to entertain the notion that we inhabit a "virtuality". This notion echoes unconventional subquantal or zero-point physics, Gnostic ideas about the Plenum and ancient Vedic concepts, such as maya that explore the ultimate nature of consciousness and matter.
This theory is not that all is one, or that the mind creates the universe, or that the universe is holistic, or that nothing really exists at all. It is that all physical reality is in essence virtual. The physical world is then a bubbling flux because, like a TV screen picture, it must be continuously refreshed to exist. This includes the phenomenal world of sensations, actions, causes and results, i.e. not just the physical body, but also the brain and the sensations and ideas it generates - including those of love, harmony, self, other selves or a universal I. So everything observed, done, said or thought is virtual, i.e., a quantum collapse.
To want to change the physical world to be of harmony and love is to want a better virtuality, a better looking screen output, while ignoring the program behind it. Wanting to "fix" the world assumes it is broken, but at the quantum level it is working perfectly, as a karmic output system of natural consequences. If each output is an input, etc, how can anything change, as this flawless machine grinds causality by trying every option?
Perhaps the way out is in. When attention is focused on the Mystery of Gnosis, another Mystery is happening in the background -- Awareness.
Consciousness information processing needs a source, so our sense of being an observer, if that is what you mean by "I", may be valid. Even in a virtuality, the choices made are real. So if we have choice, we can rewrite the program at source by changing our being. A program can't change the operating system, nor other programs, but it could alter itself. Spirituality is then not about rearranging inputs and outputs, as in politics and power, but about changing the program source, i.e. not about changing the physical world but about changing ourselves.
Note: changing the program source .... from a socially programmed persona to 'being O.B.,' the One Being of pure consciousness in individuated human form.
Kuai / Break-through (Resoluteness) 
This hexagram signifies on the one hand a break-through after a long accumulation of tension, as a swollen river breaks through its dikes, or in the manner of a cloudburst.
On the other hand, applied to human conditions, it refers to the time when inferior people gradually begin to disappear. Their influence is on the wane; as a result of resolute action, a change in conditions occurs, a break-through....
If evil is branded, it thinks of weapons, and if we do it the favor of fighting against it blow for blow, we lose in the end because thus we ourselves get entangled in hatred and passion.
Therefore it is important to begin at home, to be on guard in our own persons against the faults we have branded. In this way, finding no opponent, the sharp edges of the weapons of evil becomes dulled. For the same reasons we should not combat our own faults directly. As long as we wrestle with them, they continue victorious.
Finally, the best way to fight evil is to make energetic progress in the good.
Or, in other words, the best way to balance out an absence of O.B. ('evil') is with the presence of O.B. ('good') 
The time has arrived, if you can see it, when you must cast aside all accumulated knowledge, all teachings, all religions, all authority, even My authority as expressed in this and My other outer revelations; for I have quickened you to the consciousness of My Presence within, to the fact that all authority, teachings and religions, coming from any outer source, no matter how lofty or sacred, can no longer have any influence with you, except as they become a means of turning you within to Me, for My final authority on all questions of whatsoever nature. - Chapter 13 of 'The Impersonal Life.'
Note: In other words, the 'highest' authority is the voice of the True Self. 'My' in this instance = O.B. (One Being) = True Self. However, that is not to say that the voice of 'The Impersonal Life' is always from pure consciousness.
