Monks chosen for Tibetan Telepathy
Not all worthy (enlightened) monks have psychic powers. In fact, Satan or Mara also has psychic powers. The Buddha's enemy Devadatta, who tried to murder Buddha, also had psychic powers. Psychic powers, such as telepathy, can only be developed by individuals that have a latent disposition for them. The Buddha had many fully enlightened disciples but they all did not have psychic powers. The most lucid (Sariputta) did not have psychic powers. The disciple famed for his psychic powers (Maha Moggallana)  was said to be Mara in a past life (MN 50). In original Buddhism, psychic powers were not considered a sign of sanctity.
