Pranayama (Nadi Sodhan)
Sit in any of the meditative poses such as Padmasana, Siddhasana, Sukhasana, etc., but not Vajrasana. It should be a pose which can be comfortably maintained for at least 15 minutes. Place the hands on the knees, straighten the spine, hold the head up-right so that it faces directly forward and relax the whole body. Close the eyes and mentally prepare the mind and body for the forthcoming practice. For a few minutes be aware only of the body and the breath.
