This book is a collection of poetry centering heavily on practice of examining one's self, looking at once at one's actions and one's motivations, the examining of one's feelings. What are the things your heart longs for?
How do you respond to situations when they go well or poorly? I believe that self-examination is important and needful in order to gain a godly perspective. The word of God and the life example that Jesus lived is the standard of how a life is to be lived.
