3-iron and buddhism(possible spoilers)
In my understanding,this movie is linked with Buddhism.3- Iron refers to the well known three marks of Buddhism- impermanence,non-self, and the enlightened state of existence (nirvana). This movie describes the metamorphosis of a person on the Buddhist path.
1-Impermanence - The protagonist keeps living in other peoples houses and doesn't have a permanent stream of consciousness of his own.
2-Non-self- After going through stage 1 for a long time,he realizes that he has to obliterate his concept of self,to get rid of his restlessness.His path to non self is metaphorically described by the game of hide and seek he plays in prison.By the time he gets out of prison, he has achieved the state of non self which is metaphorically represented by him being invisible to people.
3- In the final scene he has attained Nirvana which is denoted by zero on the scale or complete extinction,emptiness,nothingness.
I was wondering if the director has said anything about this.
