Opening a Hatha Yoga class will usually entail students sitting on the ground in a comfortable position. A teacher might start with some quiet meditation, then give some gentle advice to students about paying attention to their breathing. Proper instruction on inhalation and exhalation and how it benefits the student throughout their practice of Yoga is a great way to set the tone for the class. Chanting can also be introduced at this point, as mantras can be a great way for students to focus. Some teachers open the class with the students lying down, as that is conducive to the relaxation process.
