`The most wonderful power that God could grant to man is the spirit He bestowed upon him. And naturally, every thought acts according to the power of the spirit that created it. When you know this, each of you can become a benefactor of humanity: through space, even to the most distant regions, you can send your thoughts as messengers, luminous beings tasked with helping people, comforting them, enlightening them, healing them. He who performs this work consciously gradually penetrates the secrets of Divine Creation.` [Excerpt from the text on the back cover of the edition]
