Sanathana Dharmam

Refers to the greater India during the ancient times. Also referred as Bharatha varshe bharatha khandamu. Place where karmanushtan, dharmanushtam, yagnayadamulu can be performed.

In the entire world, this is the only country where all these rituals can be performed. This bhoomi (country) is often referred to as Karma Bhoomi, Yoga Bhoomi.

e.g. If we are hungry, our feet or hands don't eat food. It is only from mouth from where food need to be taken in and it will go in to the stomach and energy will be provided to the complete body.

e.g. Consider a house which has bedroom, kitchen, hall and puja room. Before constructing the house it is just empty land and once it is constructed, we will perform specific tasks in specific room. Cooking is only performed in kitchen, we sleep only in bedroom and we pray to god in puja room and this will not change.

Likewise Bharatha Khandamu is often referred to as the puja room for the entire world.

Yagna also called as yagya/yajna is related to fire, a consciousness based vedic performance. Yagnas are performed by vedic pandits to bring prosperity, health, happieness to people or to nations.

During yagnas while chanting the mantras vedic pandits offer havana samagri (special herbal preparations) in the fire.

With the yagya performances achieved by vedic pandits everybody can create harmony in all the aspects of his(her) life. Through yagna only, one can offer havissu (food of gods) to all gods. And the place where this ritual is performed is a place where every god sits, takes his food (havissu). The satisifed gods return the favour by food (ampulus rain which will help cultiuvating food for every one not only huma beings but also animals and other living beings).

Yagna can only be performed by a human being and no one has the right to perform this. Even god can't perform this ritual and if he has to perform then he has to take human form and perform yagna.

Lord Hanumam once told in Ramayana that a person who performa 100 yagnas can become indra (ruler of all gods).

This ritual can only be performed in bharatha kandamu and no other place in the world is eligible to perform this. By performing yagna and satifying the gods, one can get rid of the reincarnation cycle and attain moksha. If this is ignore by those who are eligible for perfoming this karma, then he would be born again for more than a crore times in other forms of life (animal, plants etc). And this has been explained in bhajagovindam.

Punarapi jananam punarapi maranam,
Punarapi janani jatare sayanam,
Iha samsaare khalu dusthare,
Krupayaa pare pahi murare.

Meaning
Again and again one is born,
And again and again one dies,
And again and again one sleeps in the mother’s womb,
Help me to cross this limitless sea of Life,
Which is uncrossable, my Lord
