■ Around 593 Tibet's first unified kingdom

It is said that Songtsen Gampo established Tibet's first unified kingdom, Tibetan Empire, and introduced Buddhism to Tibet for the first time. In the 14th century royal history of Tibetan Buddhism, "Emptiness" is described as an endless empty space as a creation myth. Winds are generated from Jippo and intersect with each other to form a wind ring called a cross wind, and various things are created.
