“Contemplation,” or meditation as it is called by some, became more popular in contemporary times through the writings of Thomas Merton. The word most Christians were more familiar with was simply “prayer.”
Unfortunately, in the West prayer became something functional; something you did to achieve a desired effect—which puts you back in charge. As soon as you make prayer a way to get something, you’re not moving into a new state of consciousness. It's the same old consciousness. “How can I get God to do what I want God to do?” It's the egocentric self still deciding what it needs, but now often trying to manipulate God too.
This is one reason religion is in such desperate straits today. It really isn't transforming people, but leaving them in their separated and egocentric state. It pulls God inside of my agenda instead of letting God pull me inside of his. This is still the small old self at work. What the Gospel is talking about is the emergence of “a whole new creation” and a “new mind,” as Paul variously calls it. - R. Rohr
