Michael St. Clair speaks in Futuretalk II about creating a telepathic communication grid. Actually, I think it already exists, at least in the sense that many people get conscious guidance from their spirit guides. The first and quite much the only thing to do in order to get this for yourself, too, is meditation, I have been told by spiritual teachers.
Then, I'd like to tell you about this site, which has many interesting techniques:

Maybe this helps one step forward in creating the telepathic communication grid.
