The Journey to Jerusalem is literal, metaphoric, and archetypal. It is a believing and a discovering of Jesus' story as one's own, a process of internalizing various roads (and Roads) described in the New Testament. These are all paths to personal enlightenment, what Nan describes as a reaching to LoveConsciousness."The Road to Damascus" (Saul/Paul) involves the breaking down of the ego to receive Grace.
"Preparation" is autobiographical in nature, a gaze within to understand who each of us is.
"The Roads into and through the Wilderness" are studies of the self through the works of John the Baptist and then Jesus in the wilderness. As Jesus was tempted by Satan, we must understand what really ought to motivate, how to put temptation behind us.
"The Road to Jericho" is an awakening to what a good neighbor is by looking at the Parable of the Good Samaritan, and how we might act accordingly.
The final "Road to Jerusalem" leads to pain and the cross, but is also the road to communion with all of Creation.
