The same is not true if we say with a sense of awe that another person is not living well and that we should pray for God to help him and grant him repentance; that is, neither do we say, nor deep down do we desire that God will punish him for what he does. In this case not only do we not do harm to our neighbor, but we do him good. When someone prays for his neighbour, a good force proceeds from him and heals, strengthens and revives him. It is a mystery how this force leaves us. But, in truth, the person who has good within him radiates this good power to others, mystically and gently. He sends light to his neighbor and this creates a shield around him and protects him from evil. When we possess a good disposition towards others and pray, then we heal our fellows and we help them progress towards God.
There is an invisible life, the life of the soul. This is very powerful and can have effect on the other, even if we are miles apart. This also happens with the curse, which is a power that works evil. But if, conversely, we pray with love for someone, whatever the distance that separates us, the good is transmitted. So distances do not affect the power of good and evil. We can transmit these across boundless distances. Solomon the Wise says this very thing: 'The noise of murmurings shall not be hidden.' (Wisdom 1:10) The noise of our soul is transmitted mysteriously and affects the other, even if we don't say a word. Even without speaking we can transmit good or evil, irrespective of distance which separates us from our neighbour. What is not expressed generally has greater power than words.
Such simple wisdom. The trick is snatching those evil feelings and thoughts before they leave the building! May God help us always to disseminate peace to each other and the world!
