Customarily, the head is the most sacred part of the body. Accordingly, adornments to this area amplify and enhance this tapu.
The exaggerated scale of this heru represents the significance of that sacredness, and the consequence of the thoughts that form and radiate from the mind. This heru is rendered in a manaia form. Manaia are guides, therefore the intent is that the thoughts and aspirations are directed in a positive direction.
