Definition of Udana:
Use this as an inspiration for your meditation and mantras. ​​​​​​​
 
Udana Vayu, one of the five divisions of the life force, prana, holds special significance in spiritual practice. Udana is the upward-moving breath, which directs the flow of prana from the lower to the higher planes of consciousness. 
Udana rules the throat center, manifesting as speech and other refined expressions, and governing growth and metabolism through the thyroid and parathyroid glands. When Udana is balanced and strong, we stand tall and are joyous, enthusiastic, alert, articulate, and strong-willed. 
 
Enjoy it!
