Qi Zia

Qi is believed to be part of every living thing that exists, as a kind of “life force” or “spiritual energy”. It is frequently translated as “energy flow", or literally as “air” or “breath”.
while, Four is the sacred number of Zia, and the figure is composed of a circle from which four points radiate. These points made up of four straight lines of varying length personify the number most often used by the Giver of all good gifts.

To the Zia Indian, the sacred number is embodied in the earth, with its four directions; in the year, with its four seasons; in the day, with the sunrise, noon, evening, and night; in life, with its four divisions--childhood, youth, manhood, and old age. Everything is bound together in a circle of life and love, without beginning, without end.
