Synopsis of previous chapters:
Chapter 1; Prayer is a privilege not a right and we should pray the prayer that is given to us frequently.
Chapter 2; Prayer is simple try not to become too sophisticated to just talk to God. Use human language in human ways.
Chapter 3; Even though God is everywhere, we can use the symbolism of the church to place ourselves physically in His presence presenting our bodies as a living sacrifice.
In this next chapter Fr Tugwell deals with Byzantine prayer, and especially the Jesus prayer.
