Three Methods of Yogic Breathing 

I find it extremely beneficial to do all 3 of these every day. They each serve their own purpose, and facilitate a clear mind for the day. They reduce stress, cleanse, as well as raising one's vibrational frequency. 

* concentrate on breath

1) Cleansing Breathing
- blow nose very well
- close right nostril w/ right index 
- breathe in quickly through left nostril
- close left nostril with thumb and remove pressure from right
- breathe quickly out right nostril
- repeat 12-50 times

2) Positive Breathing
- close left nostril with right index finger
- take deep breath through right nostril for 8 seconds/heartbeats
- hold for 6 seconds/heartbeats
- breathe out right nostril for 8 seconds/heartbeats
- repeat 5-15 times

3) Breathing to Calm the Mind
- take deep breath through both nostrils for 8 seconds/heartbeats
- hold for 4-6
- exhale out both for 8 sec/heartbeats
- repeat at least 15 times, more = more result 

* practice morning and night
