Ancient mystic scientists achieved wonderful success in creating a new form of energy out of the combination of the thermal energy and the vital energy. This was called "yajnagni" (the oblatory fire). In order to understand it scientifically, one has to think along the following five aspects, viz,
(1) reasons for the varied structures of "yajna kunda" (the pit for preserving the oblatory fire); (2) the selection of "samidhas" (wood or fuel for yajna) and their specific combustion;
(3) correct pronunciation of mantras;
(4) the time of yajna; and
(5) the analysis of the properties of "Havan samagri" (the articles for oblation). The heat and light that are generated by the combustion of samidhas and the Havan samagri in the kudas of different sizes and shapes give rise to various changes in the environment. This fact has been verified by scientific experiments. There occurs a distinct change in the intensity of heat and the quality of fire produced by the change in the samidha. For example, one can easily distinguish between the quality of fire produced by the wood of Palash (Butea Frondosa) and that produced by the wood of Kikar (Acacia). It is a well-known fact that heat brings forth a chemical change in the material.
As a result, the original property of the material also undergoes change. This is the mystery behind the production of new materials by the combustion of different materials. The Havan samagri contains two types of chemicals; namely (i) those which do not burn even in the intense heat (i.e. their effective portion is not destroyed) and (ii) those which lose their identity in the oblatory fire. The chemical properties of materials are dependent on their physical state. The constituent components of materials in the solid state have less chance of interaction with that of the other materials. However, if the materials are transformed into a more subtle state e.g., vapor or gaseous state, the probability of interaction between the constituents of the two types of materials increases. If we divide one cubic centimeter of matter into one thousand minute particles, their total surface area will increase ten times. But, normally, one cubic centimeter of matter has so many particles (elements or molecules) that each one of them has a diameter of the order of nanometers.
Therefore its surface area will increase tremendously in the subtle state. Thus one can increase their capacity for reaction with other particles to a large extent. In this way, the particles that are unable to meet the vital air (oxygen) in the normal state, can easily meet the same in the vapor state. When metals like iron, lead etc are transformed into their subtle states at high temperatures and left in the air, they start burning with a brilliant glow and a beautiful red sparkling occurs. Sugar, coal, etc, in their subtle state, when they meet in the air, produce a crackling sound. Thus it is clear that the chemical activity of the materials can be increased by converting them into their subtle forms. It is to be mentioned here that minute particles have curvature. This curvature decreases as the subtlety increases i.e. the particle size decreases and hence their chemical activity increases. In this category of materials, nutmeg, mace, bigger cardamom, etc form very high quality and top ranking Havan samagri. The fragrant oil in the Havan samagri catches fire easily; and after vaporization, it expands considerably. Thus, its effect also becomes extensive. The diameter of the minute particles of these fragrant oils, in the vapor state has been found to range from 10^-6 to 10^-9 the part of that in the solid state. The effect of distilled essence of Havan samagri is not so pronounced as compared to that produced by performing Havan with the same samagri. Several compounds have been found in the vapors of Havan samagri. Some of these, e.g., aldehydes, amines, phenols, etc have already been identified. Salted materials are prohibited in this samagri, because salt (which is sodium chloride) decomposes to produce chlorine gas. The latter is as harmful to the human beings as it is to the bacteria. Ghee (milk fat) is used in the havan, in specific quantity. This has two advantages: first, it ignites the fire and controls its temperature, and second, after conversion into the vapor state it surrounds the minute particles of the Havan samagri and produces negative charges on them. The first advantage of Havan is the purification of air. The air at the site of yajna, after getting hot and light due to the high temperature of the fire, rises up. The evacuated region is filled by the fresh air drawn from the surroundings. This air is thus sterilized due to the high temperature of the fire. Sunrays of different colors have different wavelengths and hence their effect on the germs of diseases also differs. In order to see this effect, the inner walls of several canisters were painted with different colors and they were kept in such a room where a large number of mosquitoes were present. At the time of sunrise, lids were placed on all the canisters. When the lids were removed in the evening, it was found that the number of mosquitoes was least in the canister which was painted with orange color. The color of fire is also orange. Thus the utility of Agnihotra and its effect becomes clear. Scientists have discovered two types of materials for destroying the germs. They are (i) antiseptics and (ii) disinfectants. The materials in the first category protect the human beings from germs but do not kill the latter. The materials of the second category directly kill the germs. Some materials have both the properties that depend on their concentration. But the correct use of these materials is possible only by an expert. The layman may not know their use in right proportion, right concentration and hence their use may cause harm in place of benefit. Havan gas is free from this defect. Even if there is some harmful portion, it is destroyed by the vapors of milk fat and is made beneficial. The creosote, aldehyde, phenyl and other evaporable fragrant materials present in the havan gas produce the same beneficial effect. It is possible for all the people to take its advantage freely. In addition to the purification of air, the havan gas also purifies water, place etc. This gives rise to Parjanya (the shower of vitality), which, in turn, purifies and nourishes the crops and the herbs. Grains and herbs so produced make the body resistant to any viral or other infection. Even if the disease attacks the body and by chance, if it is successful in entering the body also, the virus of the disease cannot remain there for a long time; it will soon be destroyed by the self-defence mechanism of the body (immune system). The disinfectant and disease-killing properties of the havan gas have been verified by tests on hares and mice. A solution containing the virus of some disease was prepared and it was injected into the body of healthy animals. As expected, the animals were infected by that disease. The same solution was mixed with havan gas and then injected into the body of another set of animals. Surprisingly, these animals did not fall ill. This experiment has been found to be successful again and again. Havan gas has been found to be useful in agriculture also. The soil contains two types of insects, viz ( i ) those which increase the fertilizing power of the soil and (ii) those which destroy this power. The science has developed the insecticides which kill the second type of insects when mixed with the soil. Thus the first type of insects grows and the soil�s fertility improves. But this method has one disadvantage. If the insecticide is not removed immediately from the soil; it destroys the fertility-improving insects also. In another experiment, Havan gas was allowed to interact with the soil. It was found that the fertility of that soil increased tremendously and it was filled with the nourishing elements. There are elements in the havan gas, which cause the parjanya and the clouds to purify and nourish the grains and the herbs. There are two layers of air in the atmosphere. The first one ranges up to six miles from the surface of the earth and the second one goes up to 625 miles. The clouds are formed in the first layer only. The factors responsible for the formation of clouds are ( i ) the presence of water vapors in the air, (ii ) temperature, (iii) the pressure of air, (iv) the number, size and shape of dust particles and (v) the particles of smoke. In order to make the clouds pure and nourishing, it is best to get the smoke of yajna enter into them. This is why in ancient times, when the Agnihotra and yajnas were performed in large numbers, the rains were pure and full of vitality and hence the grains and herbs were also full of these qualities. It is the subtle part of the grains that nourishes the mind. Therefore, there should be no surprise, if the minds of the habitants of the ancient culture of yajna, too would have been endowed with purity and goodness. The method, by which these divinely inspired persons, devoted to yajna, changed themselves into gods and brought heaven on earth, is with us as their inheritance even today. The need of the hour is to use it extensively and wisely. Today, as the environment is getting deteriorated, as there is a hue and cry about pollution, and as the poison is spreading everywhere, its utility has increased much more as compared to that in the yesteryears. In fact, these are the polluted sentiments and motives that are reigning supreme on all the animate and inanimate beings. As a result, diseases, anxiety and friction are spreading everywhere. The only effective scientific solution to this problem has appeared in the form of Ashvamedh Yajnanushthan. Yajnagni (the oblatory fire), that is going to be produced by the combined energy of vitality and matter prima-facie that may seem a religious act, but its power and effects are extraordinary. This has been proved through extensive and successful experimentations over the last two decades by the scientist-philosophers of �Brahmavarchas Shodh Sansthan�, Hardwar. Earlier also, in order to restore the balance of nature and the society, Rajsuya- and Ashvamedha- yajnas used to be performed from time to time. The present series of Ashvamedhas is a neo-experimentation of the same old formulae of the science of yajnas. By continuing this series of, sacred deeds the poisonous portion of "tamas" will vanish gradually and "satva" will go on increasing day by day. This mahayajna is foundation and the seed of universal wellbeing and good. This is the implementation part of our dream of bringing heaven on earth. Those who talk of universal peace, progress and prosperity can be identified by how they cooperate with us in performing and completing these Ashvamedh Yajnanushthans. We should not lose this unique opportunity of a lifetime.
