The best results in Telepathy can be achieved if both sender and receiver are holding the same copper wire.
Results are even stronger if both are sitting in a Faraday cage (you heard it here first).
The easiest telepathy is for the sender to think of emotional event (positive or negative). Or think of one color for the duration of 1-3 minutes while imagining overflowing the other person with that color or placing the color in their solar plexus and head or even entire body.
With a little practice, you discover that the human being is a telepathic being.
