Yoga teachers say some odd things during class. I completely include myself in this. I've named various body parts different marine life forms: I often refer to the pelvic floor as a giant jelly fish. I've moved internal organs around the body, asking you to 'breath with your toes' or twist and 'pop the heart out and float it to the ceiling'. I have certainly said things like 'be in the moment', 'be present', 'be in the here and now'. But what do these phrases really mean?
