Ever notice that where you focus your attention is magnifed? That is, if you fear something, it seems to grow and come after you or produce whatever feeling interplay mirrors your inner self. Until awareness or conscious understanding of feelings is broadcast and received by parts of the body, little progress or change is noticed.
On another level, in terms of sending telepathic signals, how often do you sense the receiver does not get it? Some people wish for someone to come home with a quart of milk and wonder why the other person does not read their mind in transit. The most effective messages stream from heart, but the heart of what? You feel the truth inside.
On still another level, you may forget that different parts of self are interacting and communicating in more ways than you consciously follow. Those exchanges that involve consciousness may find analogy on the physical plane, but they are noticed moreseo based on sensitivity of other energetic impressions. Recall Cosmic Synchroncity.
