Confucianism is composed of knowledge, use, and Buddhism is composed of precepts, emotions, and wisdom.
The three virtues of Confucianism and the three learnings of Buddhism have a 1:1 matching structure.
That common essence is...
Knowledge and wisdom are the mental abilities to clearly see through the essence and truth of things.
A still and unwavering heart that remains unshaken, like use and affection.
The principle of causality is compassion towards others and moral restraint.
In the philosophy of unity between Confucianism and Buddhism, there was a particular perspective that viewed these three virtues and the three learnings together.
Books like "Samga Gwigam" written by Seosan Daesa during the Joseon Dynasty also contain such expressions.
Ji is wisdom, benevolence is wisdom, and function is righteousness.
However, there is a difference: the three learnings of Buddhism are vertical, while the three virtues of Confucianism are horizontal triangle relationships.
In Buddhism, the order of precepts > > wisdom is that one must clear their actions in order for the mind to calm down and move towards the essence, and only when the mind is calmed by the essence can the truth be seen and one can attain wisdom.
On the other hand, the three virtues of Confucianism are complementary and require a horizontal relationship that must be balanced simultaneously from the beginning, and in the classic Confucian text <The Doctrine of the Mean>, it is compared to the three legs of a tripod.
