This meditation is called Sunia(n) Antar. When out of focus or emotional, attention should be given to the body’s water balance and breath rate. When you are emotionally upset, practice the Kriya for Emotional Balance, a simple yogic technique you can do almost anywhere.
Remember to tune in with the Adi Mantra (“Ong Namo Guru Dev Namo”) before all Kundalini Yoga practice, and end with the “Long Time Sun Shine” song.
The Practice
First, drink a glass of water.
Posture: Sit in easy pose, place the arms across the chest and lock the hands under the armpits; palms are open and against the body. Raise the shoulders up tight against the earlobes. Pull the spine straight up from the back of the head which brings the jaw in and up.
Eyes: Close your eyes.
Breath: The breath will automatically become slow.

Continue for 3 minutes, gradually increasing the time to 11 minutes.
Comments:
Humans are approximately 70 percent water, and behavior depends upon the relation of water and earth, air, and ether. When there is a water imbalance in the system and the kidneys are under pressure, it can cause worry and upset.
Breath, representing air and ether, is the rhythm of life. Normally, we breathe 15 times a minute, but when we are able to rhythmically slow down the breath to only 4 breaths per minute, we have indirect control over our minds. This control creates a calm mind regardless of the state of affairs.
Drinking water, pulling the shoulders up to the ears, and tightly locking the entire upper area creates a solid brake that can bring balance to the brain.
