Nadi shodhana is an excellent breathing technique to calm and center the mind, bringing it back to the present moment. It helps to harmonize the hemispheres of the brain, balancing the logical and emotional sides of the practitioner's personality. Practice of this breathing technique also purifies and balances the nadis (energy channels), and ensures a smooth flow of prana (life force) through the body.
Nadi shodhana helps circulate breath through the nadis, the chakras and the brain, thus, returning the body to a state of balance. Specifically, it stimulates the ajna (third eye) and muladhara (root) chakras. It also balances the ida (left) and pingala (right) nadis, thus, enhancing spiritual progress.
Nadi shodhana helps ground the practitioner before meditation. If it is difficult to settle into the meditation, a few rounds of this breathing technique should help the practitioner find their focus.
