SUDARSHAN CHAKRA KRIYA :
Sit with a straight spine. Look at the tip of the nose or eyes closed, as you prefer.Block the right nostril with the right thumb. Inhale slowly and deeply through the left nostril. Hold the breath. Mentally chant Wahe Guru 16 times, pumping the navel point (below the belly button) 3 times with each repetition, once on Wa, once on Hey and once on GURU (total of 48 pumps). If this is too challenging, pump once per Wahe Guru for a total of 16 pumps. Unblock the right nostril. Use the right index or pinkie finger to block off the left nostril and exhale slowly and deeply through the right nostril. Continue this way.
