For example, when someone gets "red in the face" in anger, if they are linked to an EEG scanner (brain wave scanner), we can verify that their anger is not an imagination or a "subjective" sensation, as the data would show a rise in stress level in the brain. And if they are feeling relaxed, the same scanning can be done to prove their relaxed state of mind, either during meditation or listening to soft music or even track the various stages of sleep they are in. Therefore, treatment for patients with Depression or Bipolar Disorder can be done through the use of medications to control the serotonin or dopamine levels in their brains. And that provides faster relief than months and months of Ohm-ing and Ah-ing in meditation practices.
