Gurudev Sri Sri - The five types of prana in the body are Prana, Apana, Udana, Samana and Vyana. Prana is the energy in the upper part of the body, in the region above the heart. If prana is too high or is imbalanced you cannot sleep. Apana Vayu is the energy in the lower part of the body. If Apana is too high, then you feel lethargic, sleepy, and dull. Samana Vayu is in the stomach region, it aids digestion. Udana Vayu is in the upper chest and throat region, it is responsible for emotions. If Udana Vayu is imbalanced, you have no emotions, you become like a stone or you become so mushy-mushy and weak. Vyana is all over the body, it is responsible for movements in the joints, the circulation in the body. If Vyana Prana is disturbed, then the circulatory system is disturbed, your joints are not flexible, there are aches and pains. Panch Prana, the five different types of prana are present in everybody, and different pranas dominates at different times. The imbalances in the pranas are corrected during Pranayama and Sudarshan Kriya, which is why sometimes you laugh or cry as all the five pranas get activated. Knowledge is an unfathomable ocean, there is so much knowledge, but this much is enough to know, that the five pranas are present in our body and when we do pranayama and meditate regularly all the pranas get into balance.
