`Newberg and d’Aquili base this revolutionary conclusion on a long-term investigation of brain function and behavior as well as studies they conducted using high-tech imaging techniques to peer into the brains of meditating Buddhists and Franciscan nuns at prayer.

In other words, the sensation that Buddhists call “oneness with the universe” and the Franciscans attribute to the palpable presence of God is not a delusion, or subjective psychology, or simple wishful thinking.
