If we compare hoea with hau tea we can discern a common model:

Eb6-3	Aa4-46

In Aa4-46 the sky roof (top part of the glyph) is high, because it has been pushed high during spring. The proportion of the glyph between roof and ground gives the roof little vertical space, because the 'rays' take much space.

In Eb6-3 the 'rays' are bent and short, because the sky roof lies low at winter solstice. The 'roof' is not shown, because the sun (the little 'eye') is far off over the sea and absent. Instead there is a bottom part which exhibits the traits of a house - there is an inside which is dark. By lifting the right side of this 'house', though, a little light will come in from the outside.

	high ('present') sun and light spreading out
	low ('absent') sun and confined darkness
