It is an amazing thing, which possibly very few are able to believe, that there are spirits and angels who answer to the smallest muscles in man-and not only spirits and angels, but societies of spirits and angels. In fact, the more there are in a society, and the more societies of the same kind answering to the smallest muscles, the better and the stronger is their action, because "there is strength in numbers working together." Because they all work together, energy rebounds into individual people, even into spirits. This is the unbelievable thing, and yet it is most true: the heavens interact with the individual, and the individual can therefore be called a heaven, and a kingdom of the Lord, because the Kingdom of God is within each one [see Luke 17:21].
