Theory of Health and Disease in Ayurveda and Yoga


According to Ayurveda, any disease, any discomfort, or anything wrong in any part of the body, is due to an upsetting of the balance between the three humours. In Ayurveda, they believe in the theory of the Tridoshas—Vata, Pitta and Kapha—wind, bile and phlegm. These three are common constituents of the human body, and if they are in a certain proportion and balance, the body is in normal health. But if this balance, this ratio, is disturbed due to any reason, then there comes about an abnormal condition of the body. It may manifest in different ways with different symptoms. And each set of symptoms is given a label and is called by the name of a particular disease. But they say that disease is due to the imbalance of the Tridoshas—Vata, Pitta and Kapha. And most of the approach of the Ayurvedic physicians is to give some medication which will restore the balance between the Tridoshas. When this balance is restored, the person is back to normal. Whereas, in the Yogic interpretation of health and disease, they say that disease is due to the upsetting of the balance in the distribution of Prana. If the Prana becomes unevenly distributed, if it does not go to a particular place, a diseased condition can manifest in that place. Or, if the Prana accumulates too much in some place, then also a certain abnormal condition can arise. Equal distribution of Prana all over the body, throughout the body, in a balanced way, diffused—that is the condition desired. And this equal distribution means the presence of as much Prana as is required in each part. Equal distribution does not mean that Prana should be equally distributed all over the body. No. Prana is required in different proportions, in different degrees, in different parts of your body. And, if it is present in that natural state, then it is called equal distribution of the Prana. Little variations do occur in this distribution during the course of the day. When you eat food, the Prana is more concentrated over the region of the stomach. When you do intellectual work, the Prana is more active in the area of the brain. And Yogasanas bring about equal distribution of the Prana throughout the body in the desired proportion for the normal state. It is interesting to note that the Yogic interpretation of disease and the Ayurvedic theory of disease do not contradict each other. It is only one statement from two angles of vision, from two approaches. When the three humours are thrown into an imbalance, the predominance of any one of them in a particular place may draw Prana there in an abnormal quantity or may inhibit Prana from entering that particular place. From the Ayurvedic point of view, it is imbalance of the Tridoshas; and from the Yogic point of view, this imbalance of the Tridoshas brings about a disharmony in the distribution of the Prana. So, the two viewpoints are not contradictory. They are expressions of a condition from two different angles.

Take the case of a husband and a wife with one child. The husband has a certain income and he is able to look after the family with that income. As years go by, a second child comes, and the mother becomes widowed too. She now comes to live with her son and so the family grows and now they are in great financial difficulty. They are not able to look after the family. Now, why has this condition come about, this difficulty, this economic problem? We may say that it is because of the growth of the family beyond its capacity to look after itself. Or, we may say that the income is not enough, that it is not proportioned to the expenditure. From the point of view of monetary resources, the problem has arisen because the income is not sufficient. From the point of view of the family, the problem has cropped up because the members have become too many, the number of people have become too many. It is stating the same problem from two different angles. Likewise, in the case of health and ill health. When you are healthy, the Tridoshas are in balance; or you may say that the Prana is equally distributed. And when you are ill, the balance of the Tridoshas is upset; or you may say that the Prana’s even distribution is upset. So, inner health ensues out of the practice of the Asana. Due to the practice of the Asana for a long time, the Prana tends to become equally distributed throughout the body, and gradually, the normal health condition is restored to the body. This is important. And here, it is the inner health which is more vital, more important. Asana brings about inner health. It makes you impervious to heat and cold. Power of endurance is increased. Will power of the mind becomes increased. These are the benefits of the practice of Asana. And, indirectly, through the medium of the Prana, the steadiness of the body gradually brings about a certain stability of the mind, a certain steadiness of the mental activity, a certain harmony of the mental activity.

Then we come to the fourth Anga of Raja Yoga, namely, Pranayama. Pranayama is a way of controlling the Sukshma Prana within to which you have no direct access. Prana is a subtle invisible force. It is the life-force that pervades the body. It is the factor that connects the body and the mind, because it is connected on one side with the body and on the other side with the mind. It is the connecting link between the body and the mind. The body and the mind have no direct connection. They are connected through Prana only and this Prana is different from the breathing you have in your physical body. Prana is not Svasa. The respiratory breath that moves within your nostrils is not Prana. It is called Svasa Vayu. Svasa-Prasvasa, inhalation and exhalation, is of air. But then, why is the regulation of the inner breath and the outer breath of the nostrils given the name of Pranayama, when they do not constitute Prana, when they constitute only Svasa Vayu? The process of regulation of breath is given the name Pranayama, because this is the way to ultimately gain control over the subtle life-force that is present within as Prana.

How Pranayama Controls Prana

Having no direct access to Prana, the ancient Rishis evolved this method, because the outer manifestation of the inner Prana is present in the human system in the form of breath. Breath is the outcome of the movement of Prana. Breath is the outcome of the most vital and important movement of Prana. It is the Prana that moves the lungs and makes the lungs expand and contract, expand and contract, expand and contract, from the moment you are born until the moment you give up your body in death. It is Prana, the great life-principle, which keeps on this movement. It is that which pumps the heart. It does various other functions as well, pervading the whole body and being present in different ways. In performing different functions, the same Prana assumes distinct names—Prana, Apana, Vyana, Udana, Samana. Besides these, there are five Upa-Pranas or subsidiary Pranas also. In this way, this life-principle is working all the time; and whether you are awake or asleep, whether you are conscious or unconscious, automatically this Prana keeps up all the indispensable essential life-movements within you. If these life-movements are not kept going, life will not last. You will not be able to live; the body will not be kept alive. So, the Prana functions involuntarily. You do not exert to make the lungs move. It is not you who are keeping up the pumping motion of the heart. It is not you who are keeping up the bellow-like contracting and expanding movement of the lungs. You are not even aware of the movement of the lungs, not even conscious of it. It is only when something happens to you that you are aware; otherwise, you are not even conscious of it. It is this Prana, this great manifestation of Divinity, this great manifestation of the Cosmic Energy, that keeps going all these essential, vital movements in your body. The expansion and contraction of the lungs manifests in the body as the ingoing and outcoming breath. And the ingoing and outcoming breath is the symptom of the movement of the Prana, which keeps the lungs in a constant state of indispensable vital activity. So, this breath in the nostrils is due to the movement of the subtle Prana within your body, just as the movement of the second-hand, the minute-hand and the hour-hand are due to the hidden or undiscerned inner movement of the hairspring within the mechanism of the timepiece or the watch. It is because there is the constant unbroken movement of the hairspring inside that on the surface of the visible dial, the hour-hand and the minute-hand are able to move round and do their work. Now, if you want to bring about a slowing down or a cessation of the movement of the hairspring within the timepiece, you have no means of doing it, because you have no access to it. It is somewhere inside covered over by the structure of the watch or the timepiece. You cannot get at it. The only way of trying to get at it is through its outer symptom or outer manifestation. So, if you place your finger on the second-hand of the timepiece moving round in one little corner of the dial and stop it, if you arrest the second hand, gradually the movement of the hairspring also becomes arrested. Similarly, if you stop the minute-hand of the timepiece, then also, the movement of the minute-hand being the ultimate result and outcome of the movement of the inner hairspring, the movement of the hairspring gradually slows down and then comes to a stop. It is in this reverse fashion, this remote and indirect fashion, that the regulation and stoppage of the outer breath of the nostrils achieves the ultimate result of controlling and even bringing to a stop certain aspects of the movement of the subtle Prana, because the Prana is connected with the outer breath. The outer breath is connected with the subtle Prana as the latter’s ultimate outer effect. Thus, Pranayama takes you within.
