The person who sits is more ready to bring forth clear things than someone who walks or stands. Sitting means peace. Thus we sit, which is bowing in humility among all creatures. Then the individual comes to a quiet peace reaching this peace in light. The light is given in the silence wherein one sits and dwells.
The way in which we pray, when we pray really and simply, not saying prayers composed by others unless they are truly the expression of our own faith, but with simplicity talking to God in absolute confidence and sincerity, tell what our faith is.
