Telepathy derives from the Greek word
Tele meaning distance and pathy originally
pathe means affliction or experience. The idea was originally thought of in 1882 by Fredirc W. H. Myers who was a founder of Society of Psychical Research. Telepathy is the ability to read minds, implant images in minds, manipulate people by subliminal messages or even control a person.
This is apparently possible by secluding your self for many years away from any form civilisation including electrical devices or even people. After this as your mind is no longer familiar with foreign brain waves and you can pick them up using your brain. I couldn't find any reference to you being able to send your brain waves to them.
