Freedom for Enlightenment sake

In a world where biological beings have the ability to manipulate the elements, an orphan find himself in a community of nomads living peacefully and learning from the elders. After finishing his training he is bestowed the name Sindong, the youngest in the history of the temple to finish his education. Except Sindong feels that the restrictions placed upon him from his own culture does not help achieve enlightenment rather the restrictions prevents them from continuing. Sindong, being revered amongst the younger acolytes couldn't openly questions the teaching so his only choice is to declare secluded meditation and sneak out to explore.
