How to do sudarshan kriya
Do not practice sudarshan kriya within two hours of eating.
Try doing sudarshan kriya first thing in the morning before you eat or in the evening several hours after you have had dinner. This will ensure your digestion does not distract from your practice.
Find a quiet, low lit place. Pick a spot in your home that does not have a lot of noise or distractions, such as your bedroom or a spare room.
