From the introduction of the book:

"In Lent, 2015, I started a practice of writing haiku a day, to help me pray. It was a spiritual practice that forced me to put my thoughts in a fixed container of 5/7/5. So each day, I wrote and posted haiku under the hashtag, "#haikulent2015," and then "#haikueaster2015," and finally, "#haikuprayers2015". Haiku prayers became, for me, a way of lifting up my wants, needs, prayers for the world, and my hope for myself and those I love. It is no wonder that the theme of Grace is most prevalently seen in these Haiku."
