Prana – essence of Life

Prana is not merely a philosophical concept; it is in every sense a physical substance. Just as radioactive or electromagnetic waves exist even though we can't see them, in the same way, in this physical body, there are pranic waves and a pranic field. Now, each of us has a certain quantity of prana in our physical body and we utilize this in the course of our day to day activities throughout life. When our prana diminishes, sickness sets in, and when we have plenty of prana, every part of the body is in perfect health. If we have an excess of prana, it can be transmitted to others for healing or magnetism.

The inner prana can be stimulated by the practice of pranayama and thereby increased to a greater quantum. The brain requires maximum prana, and for the practice of meditation, it needs an increased supply. It is for this reason that we practise pranayama before commencing our meditation practice. If we are not able to supply plenty of pranic fuel to the brain, the mind becomes very restless and disturbed.

When the brain is receiving a deficient supply of prana, you suffer from nervous depression or nervous breakdown. Then the whole body perspires, there is trembling in every organ, you can't stand, your mind is unsteady and you are constantly thinking negative thoughts. You can't even sleep and you don't want to talk or think. This state indicates that the brain is only receiving a very small quantity of prana.

You should not think that just by practising a little pranayama you are sending a lot of prana to the brain. The process of supply and assimilation of prana into the brain is very complicated. The brain is a subtle instrument and it can only be enriched by the subtle form of prana and not the gross form. Therefore, when you practise pranayama, you will have to convert the prana into a subtle force.

Deep breathing alone is not enough to stimulate prana. By breathing deeply, you stimulate your respiratory system and the blood circulation, but if you could examine the brain at that time, you would see that it is least affected. However, when you practise pranayama with concentration, as shown by scientific studies, the brainwaves undergo a significant change and the limbic system is also positively influenced.

The brain can be split into two parts- the frontal brain and the posterior brain. The posterior brain is the instinctive brain which we have inherited through animal incarnations. The frontal brain is the seat of total consciousness. When you breathe without awareness, the breath is registered in the posterior brain, but when you are aware that you are breathing and you are consciously witnessing the whole process, then it is registered by the conscious brain, the frontal brain.

This difference seems to be very simple, but its effect is very great. Throughout life, you breathe unconsciously, just like animals, children and most other people do, excepting for the few who have started practising yoga. Now, in every case, the pranic flow is being registered in the posterior brain as if in a computer. The moment you become aware of your breathing and you begin to conduct and control the breath in a particular fashion, immediately the frontal brain registers the influence. This fact has been revealed by scientific experiments and has led us to the following conclusion. Conscious breathing has an entirely different effect on the brain than unconscious breathing. Through unconscious breathing we are definitely able to feed the whole body with prana, but we cannot supply the brain with sufficient prana for its evolution and growth.
