I agree with you that there are many similarities between Eastern and Western cultures, as if it had a common trunk. Seeing the paintings of the Buddha in the temple, although I do not understand the Korean language, I think I understand that they represent the life of Siddhartha Gautama before its conception, going through the process of enlightenment to become a Buddha, until the ceremony of his death. In truth, very similar to Christian art.
Thank you very much for your excellent posts.
PS: The detail of the headless dragon that joins the temple is very interesting. It will be that the same temple is the head of the dragon.
