Disclaimer: All the evidences presented here are based on personal research and readings of various holy books and literature research and this research has not been validated by any recognized institute.

For long people in India have been following various rituals advised to them from various sources like pundits, gurus, prvachankartas etc. without knowing the logic and science and the reasons why there is a different solution for each problem of their life through conducting different rituals.
On the other hand there are people who ridicule these practices and make mockery of these rituals and these include some very famous and reputed Samajas and dharma Gurus. They say its useless to do these things like Havan, pooja- paatth,Bhajans , kirtan , Aarti , Bhog , Chandanlepan, wearing of sacred threads( janaeuo), worshipping various idols and trees or plants .They even claim that these are all bogus things with no basis whatsoever behind them and that these practices don’t serve any purpose to the life of the people. They say that there is no effect of planetary motion on life of individuals and nothing like wearing stones for chanting a particular mantr will bring any change to life of people. But these things have been there for many millennium and are still alive, so there should be some science behind them because myths cannot survive for long is this world of where so many intellectuals like our present Dharm Gurus and various scientific samajs are present.
In this series I would like to tell you some of the finding about the rituals of Hindus, based on my understanding of their real life application and scientific reasoning. Any type of queries is welcome.
Here I present the first part in this series:
Acts---------Havan .It is performed at many occasions like janm (Birth), mrituu (Death), Shaddi (Weddings) etc. It involves the use of mantrs as per the occasion and devoting the Havan Samagri in the havan kund.
What Dharm Gurus say--------This is wastage of money and affords. God (for those societies that believe that God do exist) will not be pleased by these kinds of things; instead we should feed poor to make him happy .No Havan can bring a person a happy life. God is in our hearts and these things are just waste of resources. Now, those who don’t believe in God say that if there is no God then why perform all these rituals, man is maker of his own destiny and havans are not going to change anything .Some of them even to the extend of saying that these practices cause pollution.
Science behind-------------In Havan , the havan samagri used contains around 80 herbs including Chandan mogra, kevda ,gugal and many more .Beside these things Ghee ,kapoor (camphor) are also added. Now when these things burn in Havan Kund the smoke generated contains the collective effect of all the herbs and other ingredients .These thing have a medical significance ( as proved in various studies) so these things tend to purify the body fluids of any person sitting in the Havan or even passing it near by place . Inhalation of the smoke helps in killing the various microbial, fungal and even viral organisms that be effecting the person concerned. At the time of birth the child and his/her mother suffer various pains and distortions that may result in the production of various stress hormones, which may a deleterious effect on the health of both the persons. The smoke of Havan samagri have the ability to nullify the effect of these hormones and hence it is necessary to conduct a havan after the birth of the child .The havans should be done regularly to purify the air of homes and for good health of the family members . Now at the time of marriage it is necessary to purify the bodies of both bride and groom because it is a union of two persons in both physical and spiritual aspects so for this purpose , if their shawans (breaths and air inside body) is not pure , then this may lead to tensions ,because in today’s world there are a lot of stresses and health problems due to pollution and to nullify or to some extend pacify their effect at the time of this holy occasion, on union is very necessary or it may lead to defects in their off spring and increase the mental level stresses , as it is a major change in life of both .So to cope up with these things they need to be purified with the holy smoke of Havan . In some books it was found that this smoke also affects the fertility of the couple and hence helping in bearing healthy children. Similarly the havan done at different occasions have its own significance.
NOW THE QUESTION ARISES IF SOMKE IS WHAT ALL MATTERS THEN WHY TO CHANT MANTR AT THE TIME OF HAVAN?
WHY NOT SIMPPLY BURN THE HAVAN SAMAGRI AND INHALE THE HEALING HOLY SOME?
ALL THESE QUESTIONS WILL BE DEALT IN NEXT PART.
