One of the points of liturgical prayer
Objectivity and Godwardness

I have sometimes set aside my prayer book for days and weeks on end, and I find, at the end of those days and weeks on end, that I have lapsed into narcissism. Though meaning to commune with or reverence or at least acknowledge God, I wind up talking to myself about my emotions du jour. It is returning to my prayer book that places me. Liturgy is not, in the end, open to our emotional whims. It repoints the person praying, taking him somewhere else.
