Fundamental life force: vital energy.
▵ Prana is an intelligent energy
Whatever you do in life, how your body, your mind, and your whole system function is ultimately determined by your prana. Prana is an intelligent energy. Since prana has the karmic memory of the individual imprinted on it, it functions in each person in a unique manner. By contrast, electricity does not have memory or intelligence. It can light up a light bulb, run a camera, and do a million other things, not because of its intelligence but because of the particular device that it powers. In the future, there may be smart electricity too. If you manage to imprint energy with a certain memory, you can make it behave in a certain way.
▵ 5 Types of Prana
There are five basic manifestations of prana in the body. These pancha vayus – prana vayu, samana vayu, udana vayu, apana vayu, and vyana vayu – direct different aspects of the human mechanism. Through yogic practices like the Shakti Chalana Kriya, you can to take charge of the pancha vayus. If you gain mastery over these five vayus, you will be free from most ailments, particularly psychological ones. This is something that the world needs today.
Unless we act now, in the next fifty years, the number of people who are psychologically imbalanced, disturbed, or deranged will increase many times over, due to various factors in our lifestyles. We are handling many aspects of our lives in a grossly negligent way, for which we are going to pay the price. If you take charge of your prana, whatever the external situation may be, you will remain psychologically balanced. Right now, a whole lot of people are psychologically imbalanced, though not everyone may have a medical diagnosis.
