Answer: The quotes in paragraphs 8, and 10 must have something to do with meditation.
Explanation: I'm guessing the teacher was doing a little meditation session with his class. As it's said in paragraph 10, "It's just a way to focus [your] mind". The class must've gone through a bit of trouble or were just chaotic, so the teacher, along with them, meditated to ease their minds.
(I'm dearly sorry if this is the wrong answer, I wish you the best of luck)
