Astronomy is religion (天文即宗教). - Yonosuke Nakano

It goes without saying that the science of astronomy is the highest grade subject of learning. To my thinking, it is scientifically related to all other subjects of learning, and is the foundation of basic education for all human race. What is more, it is the primal basis that uplifts one and all men intellectually.

There is existent what is called zero, in other words incorporeity; and therefore corporeity, that is, existence, can be recognized. If there were not existent what is called zero, corporeity, that is, 'non-zero' could not be recognized. Now that there is what is called corporeity, incorporeity namely zero can be recognized.
Corporeity and incorporeity, due to the principles of duality, are regarded as a two-in-one body. This world has been and is and will be existent as a being of corporeity-plus-incorporeity due to the principles of duality. "Existence is inexistence," or "corporeity is incorporeity," is a stern truth, as one adage goes, "Matter is void."

physicographē of heaven: physico-; physio- (Gk. φύσις ‘nature’) + graphē (Gk. -γράφος ‘writing or drawing’). The sense of this compound word intended is ‘natural literature of heaven.’ As we have the letters to describe the words to express our thoughts, there are miscellaneous phenomena (in the heaven) that are displayed by numberless visible and invisible celestial bodies. Such phenomena are compared to the letters that we use for writing. Physicographē of heaven is a science in the world of spirit which corresponds to the science of astronomy in our world.
