**I would tend to agree with you, for the most part. I would also submit, though, that there are those who are considered “New Agers” that have adopted a practice because it
works.
For example, a person (Christian) hears about smudging and is told that it is a Native American practice to bless a space. Feeling adventurous, they find some sage and try it out - and they notice a difference in their house immediately. So they keep just that practice, only because it worked for them.**
I would point out that the Christian doing the above may still be seeking the exotic to some extent by going to a specifically Native American smudging practice rather than looking for or acknowledging the same thing in his own tradition. There are perfectly traditional Christian practices that are for the same purpose and done in pretty much the same way–it’s basically what a thurifer does with a thurible, though one is probably less likely to hit someone in the head with a smudge stick

.
Now if the person is unaware that such a practice already exists within the framework of his own religion, then that is a different matter, and I would not say that the person is necessarily looking for the exotic. I don’t think that it is incumbent upon the person to switch to a Christian practice upon learning that such exists if the other is working for them, but that’s just me.
To me, it would depend upon whether the person was able to see that the two practices are essentially the same and that it is largely a matter of preference whether one uses incense or sage (or a matter of allergies–I can’t breathe around burning sage or many kinds of incense, which really cuts down on the public Neopagan events that I can attend–we tend to use salt water for ritual cleansing purposes). If the person were to claim that the one worked
because it was a Native American or non-Christian practice while the Christian one does not, then I think we may be treading into New Age territory.
At root, it seems to be a case of not realizing that there really is nothing new under the sun.
That said, there is a long history of syncretism and innovation in religion. I am certainly not one to reject doing what works

. There may also be a difference between those labeled “New Agers” by others and those who personally embrace the label.
And I have to chuckle about people who are looking for things unmundane. I’m reminded of a poem written by a Zen master the day he became enlightened.
My husband likes the traditional Zen teaching: “the mountain is a mountain before practice, it is not a mountain after practice, and it is again a mountain after practice.”
My favorite Zen teaching is from a book called Zen Comics. The student rushes into the master, “Master, Master! I’ve done it! I’ve achieved detachment!” The master whacks the student upside the head with a stick. “Why did you do that?” asks the student.
“To detach you from your detachment.”
