What do you call it when you do something (may be committedly) because it is instructed by a book (divine book). When an outsider looks at it, it feels that the act is for lack of word "spiritually empty" or something of that sort.
Example: If a person goes to a temple or a church just because he is instructed to do it by a book. Would it be mechanical
He goes to do prayers. But it feels too _______ (mechanical ?)
