What does it mean to be Spiritual?

As a ceremonialist, I have found that it means different things to different people.  The question I have distilled it down to is: how do you find peace in the world?  Some people find peace through artwork such as music, dance, sculpting or painting, others by being in nature or star gazing, many by practicing yoga or meditating, more through religion or studying teachers who have long since passed, and some by simply spending time with their family or beloved.  For other individuals, peace may be found by giving back: taking action through love or service. Recently, I heard a very interesting perspective on this, this individual defined spirituality as a relationship with their soul verses a relationship with the self.  He said the relationship with self was ego based and the relationship with the soul was spiritually based. It reminded me of a quote by the mystic poet Rumi, "Do not feel lonely, the entire universe is inside you.”   So, how do you define spirituality?
