Somebody asked me, how much kinds of psychics are?
At first, who are the psychics? If somebody can read the letters by fingers, is he a psychic? May be.
If somebody has a sensitive scent? Or can sense a magnetic field? May be. Or, somebody can telepathy? Hipnotize? Fly in an astral body? Has an access to a world data base? Sure. So a definition is: Psychic is a human, who has more, than 5 senses or more developed ordinary senses.
At second, how much? A human has near 40 channels of connection with the God (Cosmos, Universum). A half of them does not work in an ordinary humans. If to count the the number of possible combinations, we will get 20!(factorial)=2432902008176640000. Plus more developed ordinary senses. Very many! Can't imagine!
