What are the cultural contents of ancient India?

The cultural content of ancient India is very rich and has played an important role in the development of world culture. Philosophically, there are the Vedas of Brahmanism, Upanishads of Buddhism and Sanzang of Buddhism, all of which are religious classics and contain all kinds of knowledge, many of which are excellent ancient literary works. The most famous literary works in ancient India are Mahabharata and Ramayana, which are far longer than Iliad and Odessa written by Greek Homer. Ancient India also made brilliant achievements in science. Mathematically, nine numbers from 1 to 9 are created, and then a 0 is added, and a method of calculating the value of the number by bit is put forward. Now we all call this number Arabic numerals. In fact, Arabs learned this from Indians. Although astronomy and astrology are mixed, they already have a calendar to measure the lunar calendar. The "five senses" (that is, five kinds of knowledge) taught by Buddhist temples are very wide and unique. This "five Ming" is a "declaration", learning to recognize ancient Chinese characters; The second is "cleverness", including mechanical and calendar calculation; The third is "Medical Prescription Qingming", which teaches Brahman's innocent words and medical knowledge; The fourth is "Yinming", which talks about knowledge such as reasoning methods and logic; The fifth is "Naiming", which explains Buddhist scriptures and causality. This multi-faceted knowledge makes Indian cultural history occupy a lofty position in the world.
