Every soul radiates an influence which charges the atmosphere all around. The more powerful the influence the wider it spreads, forcing its way even through walls. There is no barrier of water or space which can keep that influence from spreading. The stronger the influence the longer it lasts. It is not difficult for a sensitive person to perceive on coming to a room or in a house what influence it has, or to perceive, on sitting on a chair, who was sitting there before him.
