I am not sure that there are many religious implications in The Karate Kid. Made in the 1980s, the film absorbed much of the decade's fundamental challenge with effectively knowing how to deal with anything different or outside of the norm. If one really wanted to stretch it, I think that the figure of Mr. Miyagi can operate as a type of Buddhist figure. It borders on stereotype, but Mr. Miyagi represents the force of enlightenment that lives outside of established norms and traditionalist approaches. Mr. Miyagi stands in opposition to the local karate school that Daniel wants to attend, Kobra Kai. Incidentally, it is this school that the bullies attend and are taught bullying ways by their sensei. The Buddhist element here might be that the path to true enlightenment and understanding exists outside of the established and traditional path. As a student, Daniel exhibists some level of Buddhist tendencies in learning that spiritual frustration is a part of the achievement of true understanding. He does not understand the menial tasks given to him by Mr. Miyagi ("Paint the fence," "Wash the car," "Wax on, Wax off.") Yet, through these, Daniel is able to appropriate the steps needed to better understand karate and his true sense of self.
Well, it depends on what Karate Kid. I haven't seen the one in 1980, but I have seen the one in 2010. That one refers to Buddhism because when Mr. Han takes the boy up the mountain, the monks are worshipping and meditating. Does that help?
what about the movie of 2010 karate kid.? That's the one i actually confused about
