DEFINITION: “Nadi” can be referred to an artery or vein for the passage of air or energy. “Suddhi” means “cleaning.” The whole process of cleaning and purifying of nerves in the body is called “nadi suddhi pranayama.” This exercise cleans arteries, veins, arterioles, and capillaries. The whole air passage is purified and high oxygen intake is initiated in this process.
STEPS:
<READY STATE>
Sit in padmasana, sukhasana or siddhasana.
Keep the spine and head straight.
Close your eyes gently.
Keep the right hand in “prana mudra” and left hand in “cin mudra.”
Now with the right hand, close the right nostril. The closing should be such that the thumb should gently touch the area between skin and bone of the nostril.
<EXECUTION STATE>
Slowly inhale air through left nostril. Close the left nostril with ring finger.
Now, release the air gradually through the right nostril. This should be slow and rhythmic. No fast actions are allowed.
Again, inhale air through right nostril by closing the left nostril (follow the same procedure adopted in ready state) and gently exhale through the nostril.
This is one round. Perform this practice from 18 to 30 rounds.
BENEFITS:

PRECAUTIONS:
In the beginning, the body perspires and shakes, while the thigh and arm muscles become tense. Such tension should be avoided.
