hau tea

If so, then we can see the single mata in front of the standard hau tea sign as a counterpart to the thumb of Pachamama. But it resembles the tip of the Sun King's thumb:

Thumbs are on the outside (out in the light).

The 'roof' in hau tea is drawn as a broken 'string', whereas in the right hand of Pachamama there is a broken band. The originally flexible limbs broke when the smith collided with Mother Earth:

... During his descent the ancestor still possessed the quality of a water spirit, and his body, though preserving its human appearance, owing to its being that of a regenerated man, was equipped with four flexible limbs like serpents after the pattern of the arms of the Great Nummo.

The ground was rapidly approaching. The ancestor was still standing, his arms in front of him and the hammer and anvil hanging across his limbs. The shock of his final impact on the earth when he came to the end of the rainbow, scattered in a cloud of dust the animals, vegetables and men disposed on the steps.

When calm was restored, the smith was still on the roof, standing erect facing towards the north, his tools still in the same position. But in the shock of landing the hammer and the anvil had broken his arms and legs at the level of elbows and knees, which he did not have before. He thus acquired the joints proper to the new human form, which was to spread over the earth and to devote itself to toil ...

This broken band is apparently 'open' to incoming light, whereas in hau tea we can imagine the prolonged 'sides' are excluding incoming light. I think the model for drawing the tails of birds and fishes must have influenced the reading of hau tea:

open
	Ga3-8	Ab4-77	Ab6-29
closed
	Gb8-25	Gb7-10	Ab8-53

The space between the fingers (vaha) will be horizontal if the hand is kept horizontal, but vertical if the hand is turned down. The 'thread' line between 'fingers' are drawn to indicate the space between them:

Vaha Hollow; opening; space between the fingers (vaha rima); door cracks (vaha papare). Vahavaha, to fight, to wrangle, to argue with abusive words. Vanaga. 1. Space, before T; vaha takitua, perineum. PS Mgv.: vaha, a space, an open place. Mq.: vaha, separated, not joined. Ta.: vaha, an opening. Sa.: vasa, space, interval. To.: vaha, vahaa, id. Fu.: vasa, vāsaà, id. Niuē: vahā. 2. Muscle, tendon; vahavaha, id. Vahahora (vaha 1 - hora 2), spring. Vahatoga (vaha 1 - toga 1), autumn. 3. Ta.: vahavaha, to disdain, to dislike. Ha.: wahawaha, to hate, to dislike.  Churchill.

Between the fingers of Pachamama's left hand there are openings, but between the fingers of her right hand light cannot enter:

  

But, to be more correct, Pachamama has 2 left hands (one with a visible thumb and the other without).
