Well, today mathomathis will try to consolidate few points from various sources and talk about the scientific aspects of Yagna.

Scientific Use And Aspect Of Yagna

The two basic energy systems in the physical world: heat and sound are majorly found while performing yagna. In performing yagna, these two energies, namely, the heat from yagna’s fire and the sound of the chanting of the Gayatri and other Vedic Mantras, are blended together to achieve the desired physical, psychological and spiritual benefits.

Here are some of the advantages:

1. Removal of Foul Odors:

Under steam volatilization, the various volatile oils get diffused in the surrounding atmosphere along with steam and smoke. Since these oils have distinctly good smells, the foul odors are automatically neutralized. This aroma can be effortlessly smelt in the surroundings when yagna is performed. It is due to the diffusion of substances like thynol, eugenol, piene, terpinol and oils of sandalwood, camphor and clove.

2. Removal of Bacteria:

Under products of combustion, the partial oxidation of hydrocarbons and decomposition of complex organic substances produce formaldehyde, which is a powerful antiseptic. It is also interesting to note that the germicidal action of formaldehyde is effective only in the presence of water vapor, which is also produced in large quantities in yagna.

The use of formaldehyde sprays for disinfecting of walls, ceilings etc., is common and such an effect is automatically produced when yagna is performed. The oxidation of hydrocarbons produces formic acid and acetic acid, both of which are good disinfectants. Use of formic acid for preservation of fruits and that of acetic acid in preserving vinegar is a common practice.

The antiseptic and antibiotic effects of the smoke of yagna have also been examined by conducting laboratory experiments on rabbits and mice and it has been established that smoke emitted in yagna is a powerful antibiotic. Agnihotra ash is also found to purify and cleanse the water, making it fit for drinking.

3. Photochemical Process:

The vaporized products diffused in the atmosphere are also subjected to photochemical reactions in the sunlight. They undergo photochemical decomposition, oxidation and reduction reactions. To some extent even CO2 is also reduced to formaldehyde as follows:

CO2 + H2O + 112,000 cal = HCHO + O2

From an environmental angle, the reduction of CO2 caused by yagna as explained above and the liberation of oxygen cannot be overemphasized. Similar kinds of other useful reactions take place in the presence of specific radiations from the sunrays. This may be perhaps the reason it has been recommended that yagna should be performed during sunlight.

4. Removal of Insects:

There are non-bacterial parasites like flies, ringworm, dice fleas etc., which are normally difficult to deal with since bacteriocides which can be used against them are also harmful to other living organisms. Such insects are generally immune to ordinary reagents. However they either get killed or are driven away when they come in contact with volatile oils like camphor, which are diffused in the environment during the performance of yagna.

5. Effects on Plants and Vegetation:

The disinfection of air is not only useful to animal life but it also helps plant life. The aromatic substances, which get diffused in the air through Agnihotra offer protection to plant life against harmful organisms. This ensures a healthy plant growth. Agnihotra’s atmosphere and ash can be used as adjuvants in the natural farming methods – also known as the agnihotra farming methods. It is a holistic concept of growing plants in pure and healthy atmosphere and balancing the ecological cycles by performing agnihotra (yagna) in the middle of the farm and using the yagna-ash as a fertilizer. Several experiments have been conducted in the East European countries on the use of yagna ash in soil treatment. These, too, have shown positive effects and potential applications in Agriculture.

6. Role of CO2 Generated in Yagna:

The wood and fossil burning in atmosphere is always controversial because of the generation of carbon monoxide and carbon dioxide and a consequent increase in the ‘green house’ effect. On this basis it can be argued that yagna also produces CO and CO2. It should be noted here that the way in which the samidhás are burnt in yagna is a process of slow combustion. It is not comparable to the burning of coal in the factories or household fire or running of steam engines etc, where oxygen is sucked in large quantities and CO2 is emitted likewise. In the slow combustion process that takes place in yagna, a small quantity of O2 is utilized and CO2 is emitted in a quantity that poses no threat to the environment. In fact whatever CO2 is generatedis readily absorbed by the surrounding plant life and vegetation and thus the CO2 cycle is strengthened.

Another important fact to be noted is that CO2 produced in yagna is not free CO2. It is mixed with the vapors of other aromatic oils and antiseptic products. It acts as a vehicle in transporting such products to the surroundings.

The use of CO2 as a cerebral stimulant to assist patients suffering from lack of ventilation is a common practice in the medical field. Its use in controlling and curing many mental disorders is also known to medical science. Small amounts of CO2 inhaled by the persons performing yagna act as a stimulant for inhaling more and more aromatic fumes which helps in curing mental disorders.
