Did P.C. and Kristin Cast plagiarize?

Yesterday, I posted a rather jumbled piece about Marked, by P.C. and Kristin Cast. I titled that piece "P.C. and Kristin Cast Plagiarize" but, the plagiarism discussion is lost in the other thoughts I had as I read the book. Here's just the portions of their book that I think are plagiarism-at-worst or sloppy-writing-at-best.

Example 1
Page 240: Zoey is smudging Damien. She tells him:

"Smudging is a ritual way to cleanse a person, place, or an object of negative energies, spirits, or influences. The smudging ceremony involves the burning of special, sacred plants and herbal resins, then, either passing an object through the smoke, or fanning the smoke around a person or place. The spirit of the plant purifies whatever is being smudged."

I found that identical passage on over 100 different websites. The excerpts below are from here (scroll down and click on "Smudge Ceremony"):

The Smudging Ceremony

Smudging is a ritual way to cleanse a person , place or an object of negative energies, spirits or influences. The smudging ceremony involves the burning of special, sacred plants and herbal resins, then, either passing an object through the resulting smoke, or fanning the smoke around a person or place. 

 
There are a couple of other passages I looked at. Neither one is word-for-word, but pretty close

Example 2
On page (241), Zoey tells Damien:

"It's really important to remember that we're asking the spirits of the sacred plants we're using to help us, and we should show them proper respect by acknowledging their powers."

The website says:

Remember that when you smudge, you are asking the spirit of sacred plants for assistance and you must pay proper respect to their healing power.

Example 3
Later on page 241, Zoey tells Damien she prefers white sage to desert sage:

"White sage is used a lot in traditional ceremonies. It drives out negative energies, spirits, and influences. Actually desert sage does the same thing, but I like white sage better because it smells sweeter."

The website says:

Desert Sage (Artemesia tridentata). This plant will drive out negative energies, spirits and influences. Use this as a smudge to purify people and places before any sacred ceremony.

White Sage (Salvia apiana) This sage is used just like desert sage, but many people prefer White Sage because of the sweeter aroma it gives off.

Those passages may be helpful to teachers and librarians who want to discuss writing and the ins and outs of copying/pasting.
