"Our emotions and thoughts have such prpfouns effects on us because they are physically and energetically linked to our bodies via our immune, endocrine, and central nervous systems. And new research has shown that the connective tissue throughout our bodies functions as a continuous crystalline matrix in which a change in one area is immediately communicated throughout the entire system, because crystals are well-known energy transmitters and transducers.
That means that the slumped shoulders associated with sadness and grief transmit the biochemistry of 'sadness' instantaneously throughout the entire body.
On the other hand, the very act of smiling sends the opposite message. All emotions, even those that are suppressed and unexpressed, have physical effects. Unexpressed emotions tend to stay in the body like small ticking time bombs - they are illnesses in incubation."
