Tai is about imploring for favors and blessings and receiving abundance and prosperity. If you ask the gods for blessings, you will receive them, because you open your mind to see them. Some people find things in places where many others went before and found nothing. Happiness is the result of a state of mind, and going to Mount Tai is to find that.
On Mount Tai Heaven and Earth are connected, yin and yang, mind and body. There you find the space of peace.
The ideogram as a whole looks like a great mountain: Tai Shan himself,
in the West of Shandong. 'Tai wind' means West wind. He was for the Zhou
the most important of the 5 holy mountains, their most direct connection
with the divine ones.
At the top DA4 (1) the character “great”, like the great peak of a mountain. Then two hands GONG3 (2), looking like the woods embracing its flanks, and at the foot in the center “water” SHUI3 (3), the brooks and rivers running down its slopes and bringing life and prosperity to the valley.
I found a very old version of the character tai: see at right, below the moon. It is a picture of wind, blowing around a tree: the West Wind. So Tai, the 'Eastern sacred mountain' is closely connected to the West wind (blowing towards Mt. Tai, not from it).
TAI: Grand, great, eminent, supreme, excessive, arrogant, spread out and reach everywhere, quiet, ease, good luck, effortless, honorable, prosperous, too much, exaggerated, lofty; name of a mountain
