A spiritual process does not mean being serious or non-serious. "Spirituality," or a "spiritual process," essentially means you have realized that the way you know life is not enough; you want to know it a little deeper.
We pray to have our hearts opened and our purpose revealed. We pray for gratitude when our life is good and for faith when it is not so good. We pray to trust that our pain is a gift with "a very, very specific purpose."
