Sagittarians seem to have a mission to go out into the world, make significant contributions, and get to know new people. Some of the more spiritual traits of a Sagittarius individual are idealism, faith, and honesty.
They enjoy studying and discussing all different kinds of philosophy. While they enjoy change and newness, this doesn't make them shallow because they tend to go deep, where others may be content with surface answers. Spirituality is a strong component of the Sagittarian personality.
