Yes, but I bet this case goes nowhere. I find it amusing that a group promoting prayer in public schools is saying that secular mindful meditation is unconstitutional. It is secular. It doesn't include ANYTHING religious. And even if they accomplish preventing this from being taught in schools, (which I doubt) they are no closer to overturning a 56 year old precedent in Engel v. Vitale in getting school prayer back in the classroom.
In fact, if anything, the decision they seek banning meditation because they are saying that it is religious only pushes their goal further away. They are in fact arguing against a different kind of school prayer. You got to find that ironic and self defeating.
