"Penance" is a book of meditations in poetic form that was inspired by a quote from the Desert Fathers of the 4th century. "There is a huge silence and a great quiet there." For years the author made it a point to stop at the Trappist Monastery in Huntsville, Utah to absorb its silence and ask for peace. Today hundreds of self-styled pilgrims travel the circuit of abbeys and shrines to retreat from the world and find solace in their hearts. Peterson's book is a testament to the power of prayer.
