Yagya – Science Behind It

YUVA SHAKTI BANARAS/ February 10, 2015/ Science & Spirituality/



Some Scientific Aspects of Yagna – Environmental Effects

There are two basic energy systems in the physical world: heat and sound. 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.

The fumigation, vaporization and subtlisation of specific substances in the yagna-fire constitute a verifiable scientific method of sublimation of matter and expansion of its colloidal state, generates ions and energy with positive effects in the surrounding atmosphere through the specific sonic waves of the mantras.

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 non­bacterial 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 yagna­ash 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.

 7. Results of Some Recent Experiments:

A group of scientists led by Dr. Manoj Garg, Director, Environmental and Technical Consultants and the Uttar Pradesh pollution control board conducted experiments during the Ashwamedha Yagna at Gorakhpur, U.P. These experiments were set up at about 20 meters east from the Yagnashala. The samples of 100 ml each of water and air collected from the surroundings were
analyzed using high volume envirotech APM-45 and other sensitive instruments. A summary of their results ( [1] – Akhand Jyoti, Sept. ‘97 p.22) is presented below:

 7. Minerals in the Ash (Bhasm) of Yagna

Phosphorous 4076 mg per kg. Potassium 3407 mg per kg. Calcium 7822 mg per kg. Magnesium 6424 mg per kg. Nitrogen 32 mg per kg. Quispar 2% W/W These results clearly support the claims made about the role of Yagna in control of air pollution. The Deputy Director, Agriculture had submitted a technical report based on such results, recommending the use of Yagna’s ash as an
effective fertilizer.

Comparable results were also obtained by the scientific experiments conducted in about 27 large scale Yagnas organized by Shantikunj, Hardwar in India and abroad during 1993-1995.

8. Mantras — Subtle Dimensions of Sound: 

Mantras are pronounced in Yagna in accordance with the prescribed methods and rules. It benefits the persons concerned and stimulates useful vibrations and causes beneficial excitements in the environment. Besides, it makes possible the stimulation of causal energy of the materials used in Yagna to such an extent that the hidden potentialities underlying them are greatly enhanced. Articles made scared and pious with the help of Mantra, if offered by way of blessing act more effectively than even medicines. It is by involving the causal energy of material
(Havishya) before it is offered in the sacrificial fire, that exemplary successful results are produced to such an extent that even an ordinary substance possesses extraordinary specific powers. If the Havishya is simply dropped in the fire, it only creates fragrant smell and proves useful to limited extent. Without chanting Mantras it will not be possible to derive benefits, which are expected by
performing a Yagna.

When a Mantra is chanted collectively during a Yagna, its sonic power increases  exponentially due to — (i) the collision of the sound waves (generated by the Mantra chanting) with the thinnest screen ‘flame-screen’ of the quivering fire of Yagna and the high frequency vibrations generated thereby; (ii) the subtle interactions of the sound-waves of the Mantras with the cosmic energy centre (Devta) associated with their specific configurations as carry Shabdas; (iii) the fundamental thermodynamic effects associated with the fumigation of the sacrificed Havishya in the Yagna fire; (iv) the compounded effects of the vital, mental and causal energies of the people, who are in performing the Yagna.

The sound-waves, of the Mantras, instead of proceeding in their natural circular motion, are carried upwards in a spiral form by the force of the electrons generated by fumigation of the Havishya after sublation in Yagna -fire. The mutual collisions of these fast moving electrons along with thesuperimposition of the timely phased, collective sonic patterns of the Mantras result in the penetration in doubt of the ionosphere. The collective chanting of Mantras in specific rhythm in front of the Yagna flames gives rise to unique sound-waves which have infinite radiant effects in the outer space.

The subtle effects of Mantras on the consciousness are accomplished only if the reciters are authentic with respect to the proper and controlled use of their voice and tongue in conformity to the integrity and sanctity of their thoughts, emotions, character and deeds in every aspect of life. The subtle science of syllables described in the ancient Indian scriptures classifies four levels of voice (Vani) namely, the Baikhari, Madhyama, Para, and Pashyanti and highlights the importance of the spiritual practices (Sadhanas) of their realization through Gayatri and Yagna.

The wonders of ultra and infra levels of sound can be achieved by the refinement of the first and most elementary of the above mentioned four levels of the Vani. The Madhyama type works in the domain of thought waves and if refined further, leads to the subtler sounds of Para and Pashyanti, which are described as the Vanis for spiritual communications and ‘conversation’ with the Brahm. If a spiritually refined, expert performs a Yagna, the Mantras recited by him or her contain the impact of all the four awaken Vanis. Such Yagnas indeed create a spiritually charged atmosphere, which elevates the consciousness of all living beings along with harmonizing the material systems in nature.

Advancement of the on going research in the material based analysis of the effects of Yagnas along with of the subtle-science of Yagna and Gayatri would ensure bringing a bright future for humanity and for the life on this earth, as a whole.
