I am not a bharatiya, I am from the UK
Your question makes me explain a great point
Bharata Varsha actually does not refer to the only what we call now as 'bharat' or 'indian subcontinent' atleast in scriptures....It is known when one of the scripture cant remember which mentioned how the land used to exist as a total 1 clump in once but was later divided into diffferent regions which happens many thousands years after when one of the King divided. I will try to check what scripture mentioned that......
There is a
beautiful process called 'Sankalpam' in the Brahmin or Vaishnava rituals...The sankalpam is something that one doing pooja or worship first chants and then he tries to imagine the god and he invites the god into the deity before him., then he starts the actual pooja,
I took the following information from the internet, but this is the sankalpam, before that we need to understand this
1 Mahayuga = Sum of 4 Yugas (Krita, Treta, Dwapara and Kali) = 4,320,000 years. 1000 such mahayugas comprise a day-time of Brahma also known as a Kalpa. The kalpa is ruled by 14 manus in succession. The reigning period of a manu is one manvantara which is 71.42 mahayugas. There is an equivalent night-time of 4,320,000,000 years. The day-night of Brahma together constitutes one Brahma day (8.64 billion years). 360 Brahma days constitute a Brahma year while 360 Brahma years is the life of the cosmos.
The Vaidika/hindu religion is the only one of the world's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths. It is the only religion in which the time scales correspond, to those of modern scientific cosmology. Its cycles run from our ordinary day and night to a day and night of Brahma, 8.64 billion years long. Longer than the age of the Earth or the Sun and about half the time since the Big Bang. And there are much longer time scales still
We are presently in the Sveta-Varaha kalpa in the reigning period of Vaivaswatha - the 7th manu. In this manvantara we are in the 28th mahayuga. As per our Cosmology, Brahma is supposed to have completed 50 Brahma years and is in his 51st year. (100 years for Brahma) and afterthat next Brahma comes) That is why he is called "Parardha-dvaya-jivin" (ie) he lives for two parardhas. A parardha is half. Two halves make one. He is called so as he has completed one half of his tenure. These terminology makes better sense in relation to the Sankalpa.
The actual Sankalpa mantra and its meaning runs like this
".... dviteeya parardhe - in the 2nd half of Brhama's life
Svetavaraha kalpe - in the kalpa of Sveta-Varaha
