It is not news that a religious experience can be triggered by chemical means, and by electrical stimulation of certain areas of the brain. The resulting sensation is one that those who claim to have had a 'religious experience', often accompanied by emotional feelings of well-being, hold in common.
Measurements taken of the human brain during a religious fervor differ not at all between Christian, Indian Fakir, or Voodo ecstacy. What does differ is territory and culture. Those who have had 'Christ' enter their heart, were they living in India, would merely rename the concept to suit their culture.
A religionist may claim that God can easily manipulate the chemsitry of the mind, but they have a harder job explaining why what they expereinced has been experienced by the primitives for tens of thousands of years.
