What is the breath of light?

In the soft rosy twilight after a rest in sleep of about four hours, the Mother Group of the Twentieth Plane begins its day with an hour of prayer. 

They can omit sleep, and do without it, but prayer is their breath of life. They claim that they can see you when you pray. They explain this on the principle, which causes a harp string to vibrate when a string, similarly tuned and pitched, is played on in the same room. They teach that all relations are either harmonies or discords. 

Heaven is harmony―hell discord. Sin is simply discord. 

They believe that all beautiful deeds and noble achievements and purposes find fulfilment in response to sincere and earnest prayer. But prayer on the Twentieth Plane is not the selfish thing that we on earth conceive it to be. The strong and pure desire, striving up to God in harmony with the Eternal Will, this is prayer, as they conceive it. They are all, brain and heart and hand, at the divine disposal. They think with their respiration and breathe with their minds and hearts the thoughts and feelings of love and light, and all the energies of light and love work rhythmically with their desire and purpose to accomplish their prayer.
