The word ‘ Yaag ’ is very broad in the field of ‘Arya Samaj’ but it has become confined up to Agnihotr or Havan (Hom). Some persons regard it as a path/for ‘MOX’ while on the other hand orthodox consider as useless process. Actually Swami Sankracharya oppose blunt Karm-Kand. Although Yaag is a chemical process which has its social and economic importance. Actually Yaag process is based strictly according to the thoughts of ‘Swami Dayanand Saraswati’. Yaag is such a process which purify the atmosphere. As per Vedic thoughts rain may be possible under the influence of Yaag but such a change require further research. Keeping in view the above facts the concerned chemical reactions are also given about the material used in yaag. The present include history & traditions regarding yaag, feeling (thoughts) about it complete yaag process, samidha and materials used in yaag. Since beginning persons try to achieve pleasure & progress in his/her life. Scientist, philosphors and yogi persons do worship to achieve the above goal. Yaag is the refined form of such worship. persons used yaag in different forms. There are several historical articles in the support of above facts. e.g; Uttrard of vedic period and Bhraman period are famous for the organization of Yaag. In Ramayan period King Dashrath organized ‘Putrasti Yaag’. Yaag process is also popular in foreign countries e.g; Kambodia, China Emperor Suryabarman II organized KOTIHOM, LAXHOM and MAHAHOM forms of Yaag. Java, Sumatra & Malaya are famous for their Yaag organizations. In China ‘Varat’ conditions are followed during yaag process. In Japan, Dokam presented the modern ideas about yaag. In Iran, yaag is organized in some specific manners. In Rom, yaag are organized during marriage ceremony. In India, Yaags were organized before war.

STY Azeemi, S.M. Raza:-  As Ghadiadi, Klotsche Corelated colors with chakras/ Red:- Roof Chakra, orange, sacral chakra, Green (Heart chakra), Blue (Throat chakra), Indigo (Brown chakra), Violet (Crown Chakra), white (perfect color blend). chromotherapy provide colors to the electromagnetic body or the aura(energy field) around the body, which in turn transfers energy to the physical body. This make chromotherapy the most effective among various therapies.

Agnihotra is special fire performed exactly at the time of sunrise and sunset in a copper pyramid. It comes from ancient vedic knowledge. Agnihotra is said to purify the environment and specially it has been found to have prefound impact in mitigating water pollution problem.

Satya Prakash (KVRF) Publication calicut (2011):-

Chemistry in agnihotra play a major role in our day to day life. Therer are several historical evidence in the support of above data. Eg. of vedic period and bhraram period are famous for the organization of yaag.

trch oral Biol 56 (2011) pp. (650- 654) :- oral bacteria are known to produce many short chain fatty acids ( SCFAs, isobutyric, butyric, isovalenic, propionic, lactic acids) 4, 7,8 and even LCFAs (myristic acid, palmitic acid) as end products of their metabolism.

P Bansal, R. Kaur, V. Gupta, S.Kumar, R. Kaur, J. Epilepsy Res, 5 (2015) pp. 33-45:- In older time Rishimuni ancient scholar and physicians used to recommend hawan for mental peace and well being . Gayatri Mantra also tells that Sughandhim (aroma, fragrance) pushtivardharam (gives rise to good wealth)om triambkum yajamahe, sughandhim pushtivardhanam, urvarukmev vandhanaat , mrityu mokshey mamritaat!

As per the author's knowledge, the latest reviews are not available on this topic and the given literature is sufficient to discuss this study. 

It may be discussed in following parts:- R. YAAG SHALA- S. The floor of it must contain pure mud (clay) and it must be 16yard x 16yard in size. It must be covered with the help of 20 poles whose height must 10 yard. There must be total 4 gates (i.e; one gate in each side). T. YAAG KUND- U. It may be prepared by soil (clay), iron, copper or gold. Height of this kund must be 16 angle. Width at bottom must be 4 angle but at the top must be 12 angle. In the case of grand Yaag different dimensions of Yaag Kund are given in Satyarath Prakash. The above said dimension are strictly scientific in nature. V. YAAG CONTAINERS W. Generally copper container is used in this case because it is cheep in cost and antigermical in nature. other materials may be wood, gold & silver. Chamcha, chimta, Ajayasthal, proxniya part, sakalya part and achmani are also used during Yaag process.

First of all all the above said articles are made completely pure (free from any impurity). Now fire is ignited with the help of Camphor. Now concerned Ved- mantras are repeated before each process.

SAMIDHA-

In India some specific wood pieces are used as samidha in yaag process as per Swami Dayanand are Chandan, Palas, Pipal, Bad, Gular, Aam etc. In England Oak wood is used as samidha. While in Afganistan badam wood is used as samidha. Main portion of wood in cellulose (C6H10O5)n. It also contain some fraction of gum, volatile oils, acids, fatty acids & some inorganic compounds. Percentage of oil in different woods are as under-

Table -1

Wood	percentage of tenin
Bad	10.9
Gular	14
Pepal	3.8

while on the other hand the percentage compositions of  wood and coal are as under-

Table-2

In wood
Oxygen	43
Nitrogen	0.04
Hydrogen	6.0
Carbon	49
In coal
Oxygen	12
Nirogen	1.0
Hydrogen	5.0
Carbon	82

thus on the basis of above data wood is preferred in place of coal in Yaag process. Since coal produce higher percentage of CO gas on combustion –

 2C(s) + O₂(g)                          2CO(g)

when combustion of wood take place during yaag then different useful chemical are produced which work against different disease eg.

Table-3

Wood	Illness treated
Butea frondosa ( Dhak )	Kidney infection , anti – germ interstinal
Ficus religiose (pipal)	Dah , Pith , Kaf , blood infection
Ficus glomerata (Gular)	Blood infection , kaf , pith
Mangifera Indica (Aam )	Anti – diabetic , bloodb infection
Santalum Album (Chandan )	Anti – inflamatory , blood infection
Ficus Bringabnsis (Bad )	Fever , sources of energy

Thus the wood used as samidha are very useful against different diseases because they produce useful gases on combustion during Yaag process. Their chemical composition were discussed by Demok, Kertikar and chopola in detail.
SAMAGRI
As per Swami Dayanand samagri must contain following four properties -
1. They must have pleasant smelling chandan, Kasturi, Agar, Togar & Jayfal.
2. It must contain proper amount of the following eg. Ghee, Milk, Fruits, Rice,  Wheat etc.
