There are three shame in life, and the first shame is not understanding astronomy and mathematics.
In the “Ri Zhi Lu”, it is also lamented that “for more than three generations, everyone is an astronomer, and then literati and scholars are confused and unaware.”.
The ancients said that they did not understand phonetic exegesis, astronomy and calendar, and could not read ancient books.
Although modern people read fewer ancient books, classic training should be a necessary item, and learning classics cannot be separated from astronomy and calendar.
Astronomical applications can be mainly divided into two aspects. The Records of the Grand Historian uses the calendar as a step learning method and the elephant as an empirical learning method.
To truly learn the Book of Changes and understand it from its roots, one must understand astronomy and calendar. To learn traditional Chinese medicine for health preservation, one also needs to learn astronomy and calendar.
My friends often ask me, “I want to learn the Book of Changes. What are the ways to improve my spiritual state?”?
My answer is to read ancient books and learn astronomy and calendars.
Of course, studying astronomy also has a very important significance: to view time and space and the world with a romantic and ancient, starry and vast mind.
