4. The impact of lightning and thunder - as if there was a pair of gods 'talking' to our eyes and ears - apparently makes nature wake up. A change of state mostly follows with fresh air and sun returning.

The kava glyph type is designed as a zigzag pattern, much like that written in lightning on the dark stormy sky.

Lightning and thunder work magic together creating sunligth and rain. Sunlight and rain are related:

"On February 9 the Chorti Ah K'in, 'diviners', begin the agricultural year. Both the 260-day cycle and the solar year are used in setting dates for religious and agricultural ceremonies, especially when those rituals fall at the same time in both calendars.

The ceremony begins when the diviners go to a sacred spring where they choose five stones with the proper shape and color. These stones will mark the five positions of the sacred cosmogram created by the ritual. When the stones are brought back to the ceremonial house, two diviners start the ritual by placing the stones on a table in a careful pattern that reproduces the schematic of the universe. At the same time, helpers under the table replace last year's diagram with the new one. They believe that by placing the cosmic diagram under the base of God at the center of the world they demonstrate that God dominates the universe.

The priests place the stones in a very particular order. First the stone that corresponds to the sun in the eastern, sunrise position of summer solstice is set down; then the stone corresponding to the western, sunset position of the same solstice. This is followed by stones representing the western, sunset position of the winter solstice, then its eastern, sunrise position. Together these four stones form a square. They sit at the four corners of the square just as we saw in the Creation story from the Classic period and in the Popol Vuh. Finally, the center stone is placed to form the ancient five-point sign modern researchers called the quincunx ...

Later on in this series of rituals, the Chorti go through a ceremony they call raising the sky. This ritual takes place at midnight on the twenty-fifth of April and continues each night until the rains arrive. In this ceremony two diviners and their wives sit on benches so that they occupy the corner positions of the cosmic square. They take their seats in the same order as the stones were placed, with the men on the eastern side and the women on the west. The ritual actions of sitting down and lifting upward are done with great precision and care, because they are directly related to the actions done by the gods at Creation. The people represent the gods of the four corners and the clouds that cover the earth. As they rise from their seats, they metaphorically lift the sky. If their lifting motion is uneven, the rains will be irregular and harmful." (Maya Cosmos)

One of the effects of kava drinking is to enhance the sensitivity of the eyes - light appears to be growing.
