Humility and its correlation with human spirituality is defined in some depth in the book The Power of Humility, which describes twelve characteristics of humility from a generalized perspective, as opposed to the expectations of an organized religion. [2]
The book indicates that humility is a way towards inner peace, and outlines what the authors believe are the steps toward achieving such.
Spiritual views on humility are contrasted with religious views on humility in that spirituality, by definition, is often personal and thus has a direct impact only on one’s particular self or state of being, whereas religious views are generally considered more rigid, wherein a specific set of rules or laws are put in place to govern how modest or audacious is appropriate in a given situation. in other words, spirituality is an avenue through which humility can be shown or explored, but, once more by definition, is not a governing force unless one chooses it to be.
It is generally considered more pleasant to be humble, as being boastful or obnoxious may have the natural consequence of annoying others. This may be why humility is considered a virtuous state of being.
