1. The intake of nutrition is necessary for growth, be it a delicious meal prepared in the earth oven or the fertilizing dung spread out on the fields.

In the calendar of daylight the morning sun is growing in strength up to noon, and the kai hand gesture is therefore used:

a.m.			noon
Ha5-52	Ha5-56	Ha6-1	Ha6-2

The nutrition sun is taking in may be far from obvious, but not so for the ancient mind:

"... The life-force of the earth is water. God moulded the earth with water. Blood too he made out of water. Even in a stone there is this force, for there is moisture in everything. But if Nummo is water, it also produces copper. When the sky is overcast, the sun's rays may be seen materializing on the misty horizon. These rays, excreted by the spirits, are of copper and are light. They are water too, because they uphold the earth's moisture as it rises. The Pair excrete light, because they are also light ...

'The sun's rays,' he went on, 'are fire and the Nummo's excrement. It is the rays which give the sun its strength. It is the Nummo who gives life to this star, for the sun is in some sort a star.' It was difficult to get him to explain what he meant by this obscure statement. The Nazarene made more than one fruitless effort to understand this part of the cosmogony; he could not discover any chink or crack through which to apprehend its meaning.

He was moreover confronted with identifications which no European, that is, no average rational European, could admit. He felt himself humiliated, though not disagreeably so, at finding that his informant regarded fire and water as complementary, and not as opposites. The rays of light and heat draw the water up, and also cause it to descend again in the form of rain. That is all to the good. The movement created by this coming and going is a good thing. By means of the rays the Nummo draws out, and gives back the life-force. This movement indeed makes life.

The old man realized that he was now at a critical point. If the Nazarene did not understand this business of coming and going, he would not understand anything else. He wanted to say that what made life was not so much force as the movement of forces. He reverted to the idea of a universal shuttle service. 'The rays drink up the little waters of the earth, the shallow pools, making them rise, and then descend again in rain.' Then, leaving aside the question of water, he summed up his argument: 'To draw up and then return what one had drawn - that is the life of the world' ..." (Ogotemmêli)

This central thermodynamical law of life (light and water in cooperation) explains why the kai person has his feet designed like his hands - to indentify his locus of output. There must be an output in order to balance the input. 3 fingers identify the daylight, and there must be 3 toes for its outlet.

In the calendar of the daylight, though, the output of the sun comes during p.m. in form of another type of hand gesture:
