“Zentao is a transformation of the Tao symbol. Instead of having only 2 elements (Yin and Yang) is made up of 5 colors of the elements of feng shui (huo-fire, tu-earth, jin-metal, shui-water, mu-wood). The 5 elements have energy centers placed on their head and they rotate in a circle around a perfect 5-pointed spiral.”

“The symbol also draws strength from symbolic Pythagorean pentagram (a 5-pointed star inscribed in a circle).

The circle is open and emerge from the rotating symbols within.

The 5 elements symbolize the elements of the universe (either as water, fire, earth, air and spirit that as natural elements of feng-shui).

The 5 elements also symbolize the 5 historical schools of Zen.

The ancient symbol of Pythagorean pentagram with top-up is a sort of western Tao because it expresses the relationship between the two complementary universal (male-female, hot and cold, day-night, etc. ..) and as an expression of power, energy that moves and changes the universe.

The central spiral is the symbol of Qi (氣 Chinese pinyin, while pronounced ki 氣 Japanese kyūjitai). The spiral is both sun, star, galaxy, cosmos, and each cyclical phenomenon that evolves and is repeated in a similar way but never equal to itself (eg the planetary revolutions, the seasons, biological cycles, etc.)..

The 5 white lights that affect the elements are the energy that permeates all things and that changes everything constantly.”
