All the angels are amazed at humans, who through their holy works appear clothed with an incredibly beautiful garment. For the angel without the work of the flesh is simply praise; but the humans with their corporeal works are a glorification! Therefore the angels praise humans' work.
Contemplative life is the putting together of vision and action. Vision alone, meditation alone, is not true contemplation. We must put vision into action. Not just monks, but all of us are called to contemplation in this full sense. If we want to live healthy lives, we have to build into our daily life moments of vision, and let our actions be formed by that vision.
