Sit in Padmasana or Siddhasana. Close the mouth. Inhale slowly through both the nostrils in a smooth, uniform manner till the breath fills the space from the throat to the heart.
Retain the breath as long as you can do it comfortably and then exhale slowly through the left nostril by closing the right nostril with your right thumb. Expand the chest when you inhale. During inhalation a peculiar sound is produced owing to the partial closing of glottis. The sound produced during inhalation should be of a mild and uniform pitch. It should be continuous also. This Kumbhaka may be practised even when walking or standing. Instead of exhaling through the left nostril, you can exhale slowly through both nostrils.
