"Science cannot tell us if God exists only in our imaginations or as an entity beyond our comprehension. So why do some scientists continue the search for the roots of religious experience? Shouldn't such claims of oneness with a God be judged by their fruits, rather than their roots, as William James wrote in The Varieties of Religious Experience? Researchers may persist at these efforts because such studies offer the potential to alter our lives. In principle, these findings could lead to methods—call them "mystical technologies"—that reliably induce the state of spiritual insight that Christians call grace and Buddhists, enlightenment. Already Todd Murphy, a neuroscientist who has worked with Persinger, is marketing the "Shakti headset," a stripped-down version of Persinger's God machine, for "consciousness exploration." Electrodes implanted in the brain that electrically stimulate specific regions are now being tested as treatments for depression and other mental illnesses; conceivably this technology also could be used to induce mystical states."

There's always a risk that when you post a quote from something complete with a link to the source that you'll be shown up for not having revealed the context.....

The theories described below illustrate the diversity of scientific approaches to understanding religion. All these theories are tentative at best, and some will almost certainly turn out to be wrong. The field suffers from vague terminology, disagreement about what exactly "religion" is, and which of its aspects are most important. Does religion consist primarily of behaviors, such as attending church or following certain moral precepts? Or does it consist of beliefs—in God or in an afterlife? Is religion best studied as a set of experiences, such as the inchoate feelings of connection to the rest of nature that can occur during prayer or meditation? Comparing studies is often an exercise in comparing apples and oranges. Nonetheless, the science merits close attention.

So it's an interesting area to study but too vague a concept to really get anything useful from as far as I understand it.
