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.
True friendship exists when human beings share a love of goodness and truth. Two friends alone, like two legs on a table, offer a wobbly situation at best. But two friends anchored to a third, spiritual center form a rock-solid foundation to support everything that comes: hardship, suffering, exaltation, love. True friendship between two human beings exists only when there is a third Friend present: call this third friend God, or simply the Sacred.
