The means which Souls use to discover each other is the broad subject of communication, including intent, telepathic exchange and insight, intuitive two-way understanding, love, taking visual bearings on the motions around one, perceptions of tactile, sound, light, warmth, motion, electrical sensation, significance of every description. All these are communications. They can be found in the ether between bodiless souls or in the way someone hauls his little red wagon or in the speeches in Congress or the whispers in the trenches of Syria or the laughter of lovers or the bullets of war. Somewhere between those extremes lies the man or woman you last spoke to, their parents, your mailman, the dog and every life- form. These states, emotional or spiritual, are the feelings generally seen as affinity states.
Dry theory runs on forever in the human brains.
The simplicity is that we ARE connected with all things, because we share the entire universe of life energy, like multiple rivers feeding a single sea. The connections between them, like streams between one and another river, form the net of life.
