Xu Zhe? Tianlang? Is it passive or active? Is it the dominated, or the dominating one? Is it an illusory world or a real world? The path to salvation lies within. Nothingness gives rise to two phenomena, two phenomena give rise to four images, and four images give rise to the Eight Diagrams. The five elements and eight trigrams break up the universe, and the sun, moon, yin and yang establish the heaven and earth. Only by continuous growth can we break through the emptiness! Step into the universe!
