In time, there are layers and layers of beings. Some are seen and some are unseen. They are sometimes seen by the human eye, but most often they are sensed. There is that feeling that someone is there, or perhaps a change in the atmosphere, or a feeling of a cold breeze. This sensing is shared by many, but felt/seen by few. There is a reason for this. Too much distraction for those who could not handle it would place an unnecessary burden on the individuals who are not ready for the experience. Of what benefit is this to those who cannot see or feel them? Perhaps it is like taking a little drink of water at a time. Some do not want to be bothered and unless the situation is dire, that request is honored. For those who are receptive, it seems the best approach is to be aware and observant but alert to imposters. As you become calm around those who are not in a body, you open up an avenue for heavenly insight. Depending on the spiritual advancement of the spirit, you may have or hear an ordinary conversation or sentence whereas a more advanced soul would have more to say. Have faith in your own being, your own self, your own knowing. Listen and then use discernment as to the message given.
