There are a few books on Amazon about remote viewing. The first one I ever read was Psychic Warrior. It is a true story of the CIA’s Paranormal Espionage Programme. Very gripping and exciting.
Remote viewing has been used by countries in the past, to see what the competition is up to, so to speak.
If you have read anything about astral travel, you may have an understanding of remote viewing. The subjects are given map coordinates, before going into a trance like state, and taking themselves to the intended destination.
At first they travel to nearby locations and eventually they learn to travel across countries and continents. They are debriefed after their travel to find out what they have experienced.
Learning to travel remotely is possible even if you are not a government agent. You just have to set your sights a little lower. Get a good book which explains the nitty gritty of the mechanics.
Start small by moving into the next room and then the next building. Maybe then it can be the next street and the next town. Who knows how far you may travel without leaving your chair! There are sometimes groups who like to share their experiences. You may find like minded people on line.
