Here is a very useful information sent by Sri Rangaraj Ramaswamy in one of his postings in andavanyahoogroups. For a wider coverage, I am repeating the same message in this blog as well ashramam facebook.
WHY VISIT TEMPLES ?
There are thousand and thousands of temples all over India in different size, shape and locations but not all of them considered to be in the Vedic way.
Generally the temples are located in a place where earth's magnetic wave path densely passes through. It can be in the outer skirt of the town/village or city, even in middle of the dwelling place, or on a hilltop. The essence of visiting a temple is considered here. For every Srivaishnava, it is a must to pay a visit twice every day to the Vishnu Temples in their locations. In simple terms, these temples are located strategic to a place where the positive energy is abundantly available from the magnetic wave distributions of north/south pole thrust.
Because of its location where high magnetic values are available, the Main Idol is placed in the core center, and also because they place a copper plate written with some Vedic scripts, which is buried, beneath the Main Idol's placement known as "Garbhagriha" or Moolasthan, the copper absorbs the earths magnetic waves and radiates to the surroundings. Thus a person who regularly visiting a temple and taking clockwise rounds of the Main Idol's placement, automatically receive the beamed magnetic values absorbed in his body. This is very slow and a regular visit will make him absorb more energy. What scientifically it is known is positive energy. In addition, the Sanctum sanctorum is completely enclosed on three sides. The effect of all energies is very high in here. The lamp that is lit radiates the heat and light energy. The ringing of the bells and the chanting of prayers gives the sound energy. The fragrance from the flowers, the burning of camphor give out the chemical energy. The effect of all these energies is activated by the positive energy that comes out of the idol. This is in addition to the north/south pole magnetic energy that is absorbed by the copper plate and utensils that are kept in the Moolasthan known as grabagraham. The water is used for the Pooja is mixed with Cardamom, Benzoine, Holy Basil (Tulsi), Clove, etc. are mixed that is known as "Theertham". This water becomes more energized because it receives the positive ness of all these energies combined. When persons go to the temple for the Deepaaraadhana, and when the doors open up, the positive energy gushes out onto the persons who are there. The water that is sprinkled onto the people passes on the energy to all. That is the reason why, men are not allowed to wear shirts to the temple and ladies have to wear more ornaments because it is through these jewels (metal) that positive energy is absorbed in ladies. It is proved that Theertham is a very good blood purifier, as it is highly energized. Hence it is given as prasadam to the devotees
Lost energy in a days work is regained this way and one gets being refreshed slightly. The positive energy that is spread out in the entire temple and especially around where the main idol is placed, are simply absorbed in one's body and mind, for those who take a regular clock-wise round circle every day. In addition at the temples they offer holy water about three spoons. This water is mainly a source of magneto therapy kind because usually they place the copper water vessel at the Garbhagriha. It also contains the values of cardamom, clove, saffron, etc to add taste and Tulsi (holy Basil) leaves are put into the water to increase its medicinal value! The clove essence protects one from tooth decay, the saffron & Tulsi leave essence protects one from common cold and cough, cardamom and benzoine known as Pachha Karpuram, acts as a mouth refreshing agents! This way, one's health too is protected, by regularly visiting the Temples . The entire thing just become more energized locally, that the visit and consuming the holy water and the other offerings are worth for the visitor's health and longevity.
Apart from the above facts, each and every round taken in the temple is just simply burning fats in human body and in those days people regularly visited temples and never used to get sugar complaints/diabetic! In addition to it the Vedic chanting helps visitors some refreshing feeling in body and mind thus achieving mental peace, which is the ultimate aim of every soul. And in those days, it was quite rare, you'll see persons with Sugar level high in their blood. In fact, the regular round trip to the temple itself protects one from increasing sugar levels.
