Once you grasp the nature of unconditional love, you realize there is a higher order of complexity that is unfolding within human consciousness as a whole. Then you receive the next gift of the angel light -- humility, perhaps the hardest gift to accept. In the angel light, there is no room for self-importance -- it is, in fact, a major obstacle.

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.
