Tirupati Balaji, that place in the world where more than one hundred

thousand devotees come every day. But think about it,

thousands of years ago from today, without any machines,

at a height of three thousand feet,

where there was not even drinking water,

how was such a massive temple built there? Today we will see how our ancestors,

by using the engineering of the divine,

erected a temple that has stood firm for centuries.

First, let us talk about the foundation.

The mountain on which the temple stands is not an ordinary mountain.

Science believes that this is an Aprachian unconformity.

Meaning this rock is about two billion ten crore( 2.1 billion) years old,

and this ground is shockproof.

The effect of earthquakes here is almost negligible.

The proof of this is the natural arch there. There is a natural stone

arch here that is one billion fifty crore( 1.5 billion) years old.

This is the very solid ground on which the temple rests.

The ancient architects knew this fact.

They knew that the house of God had to be in a place that would remain safe even in

an apocalypse. Now look at the structure.

No cement has been used anywhere in this entire temple.

The dry masonry technique has been used here.

Meaning, by cutting massive granite stones,

they have been designed so that they lock into one another.

This creates a box effect. Even if the earth ever shakes, these stones do not break,

instead they move slightly together and then settle back into place.

Now look up at the Ananda Nilayam Vimanam, that golden dome.

It is not just beautiful, it is actually a masterstroke of engineering.

When this dome was being made heavier and larger, the engineers

felt that the old 10th- century wall would not be able to take the load.

So they did retrofitting. Meaning, all around the sanctum

they raised another wall that bears the weight of this heavy gold tower.

And listen to this,

The gold is not directly on the stone, it is on copper plates.

But when copper and iron meet, rust forms,

which in science is called galvanic corrosion. In the 1958 renovation,

the old iron nails were removed and non- corrosive materials were used,

so that the shine of the gold would remain intact for centuries.

Now let us talk about the mystery of the sanctum’s temperature,

which amazes everyone. No matter how hot it is outside,

it always stays cool inside the sanctum.

Many times, moisture has also been seen on the idol.

Behind this is an amazing calculation. The temple walls are 1.25 meters,

that is, about 4 feet thick.

This thickness does not let the outside heat enter at all.

Ventilation has intentionally not been provided inside,

so that this microclimate is maintained.

When the air inside is locked and the worship rituals are performed,

this cold granite stone holds the moisture in the air.

People may call this condensation, But for devotees,

this is the idol coming to life.

And maybe the engineers deliberately designed it in

such a way that the devotee feels the presence of God while standing there.
