About five months ago I was in  conversation with a group of Americans. One of them asked me a very  intriguing question,  how did the Indian civilization survive  thousands of years unlike the Greek or Roman ones? 
I found the answer in a book by Shri  K M Munshi titled “Foundations of Indian Culture”. The author was  founder of the Bhartiya Vidya Bhavan, eminent lawyer, scholar, writer  of modern Gujarati literature and one of those involved in framing  the Indian Constitution. Munshiji was also behind the eleven volume  magnum opus titled History and Culture of the Indian People published by the Bhavan. 
This article was compiled in 2001  and edited in 2017. It is completely based on the above book for  which I deserve no credit. Wherever necessary, I related it to  current events. 
Significance of Culture
Last fifteen years or so have  brought forth many questions - Where do Indians come from? Why is  family such an important part of India's social structure? Why did  India not export its culture by the power of the sword or why do  followers of Indian religions not convert? And so on. 
Unless we have knowledge about  Indian culture, we will not be able to understand who we are, why we  behave in a certain way and what do we yearn for. Instead of letting  these ideas take branches of their own, we’ll try to explore these  questions ourselves and present a sound answer for each one. People  from foreign lands find Indian culture fascinating and often ask  intriguing questions which compel us to think.
What is Culture?
‘It is the sum total of values  expressed through art, religion, literature, social institutions and  behavior, the overt acts of individuals and mass action inspired by  collective urges.’ Its first characteristic is continuity. 
A distinctive culture comes into  existence when people develop a continuous way of life. This is  expressed in many ways like common traditions and norms of conduct  /institutions (marriage, family) /memory of triumphs achieved  (Mahabharata fought at Kurushetra between the Pandavas and Kauravas).  For e.g. where ever we go in India there are certain accepted norms  of conduct.
The most important characteristic of  a vital culture is a common outlook among the people, who when faced  with adversity, difficulty, can generate a collective will to action.  However, when the collective will to resist is weak the culture  starts decaying. 
You might realize that  a common  will to tackle the country’s problems seems to be  lacking in India  today. We have Hindus who look up to  Maharana Pratap or Guru Gobind  Singhji for inspiration while Muslims look up to Akbar and Aurangzeb.  How then can a collective will develop unless common heroes bind us  all together? Nations are formed by amalgamation of identities and  not by harping on differences continuously.
With the passage of time scenarios  change, society-cultures come under pressure to respond. When such an  event occurs, it is up to the more prominent members among the  dominant minority to adjust their outlook, institutions in accordance  with its Central Idea. The majority should also become tolerant of  other minorities. When this does not happen the culture dies and with  it the people. (note that minority does not mean Muslim as is  understood in India today). 
Take the case of a modern Greek or  Roman. Both these cultures were overwhelmed by the West and are  nowhere near the spectacle of their ancient culture. 
The vitality of a culture cannot be  passed down from father to son through a Will. Its values have to be  recaptured afresh by every generation and would be subject to  constant reinterpretation. If a culture is living the young would be  impacted by it.
At the outset must state that I do  not believe in the Aryan Invasion Theory even though the respected  Shri Munshi might have referred to it. This book was written in 1962.  In the last ten odd years the invasion theory has been debunked, a  fact i.e. widely accepted today. 
Gathering of Elements – The  Vedic Aryans
What is important in the  understanding of a culture is the way it is approached.
A humble way would be to ask the  natives, how did it come into existence? What was the central idea  behind it? Another way would be to look at the conditions of the time  in which it is studied. What changes are to be made in the old forms  to adjust with present times? Another approach is that of the modern.  If I had been Vyas of 3,000 years ago with the outlook of today, how  would I have shaped this culture?
To get a true understanding of  Indian culture we need to understand the conditions under which it  evolved, understand how it came into existence, the forces that led  to its growth etc.
How did Indian culture come to be  founded?
Millions of years ago, the land  north of the Aravillis was under a sea named the Tethys. Gradually,  the Himalayas arose out of the sea. As time passed a huge land mass  arose with rivers flowing out of the mountains bringing silt down  along with them. In this way modern day North India was created, with  silt deposited plains. Its immense fertility attracted people from  distant lands. The prosperity of North India is linked to the  Himalayas. 
Unfortunately forest fires coupled  with deforestation have lead to lower rainfall and warmer climate.  Unless this trend is reversed, we have a problem on our hands. In  Kumaon was told that the British popularized the growth of pine  trees, which catch fire easily. 
Indians are a combination of various  tribes. Negritos came from Africa, Proto-Australoids from Early  Mediterranean, Mongolians, the Later Mediterraneans identified with  Dravidians, the Alpines considered pre-Vedic and Vedic Aryans. U.P.  and Bihar were occupied by a race called Copperheads. It is believed  that the Nagas, Asuras belonged to this stock.
The languages they use are Kol  limited to hill tribes, Sino-Tibetan limited to East India and the  Aryan and Dravidian languages.
Before 2000 B.C. the Aryans entered  the face of history and spread over Asia and Europe. Indo-Iranians  entered India through Afghanistan. Zend Avesta, the sacred book of  the Parsis contains several verses that are found in the Rig Veda.  The Vedic Yama is the Zend of Avesta and so on. 
According to Bhagwan Dass Gidwani,  author of the book “Return of the Aryans,” Aryans were originally  from India and migrated to various parts of the world. Swami  Vivekananda too said that Aryans were from India.
Aryans are believed to have re -  entered India around 1500 B.C. For about the next five centuries they  fought a war within themselves and with the Dasas, Asuras etc. During  this period there was an intermingling of customs, beliefs and a new  harmony evolved.
The Aryans brought with them  cultural vitality and influence. Their culture flourished in the  Vedic Ashrams that were situated on the banks of river Saraswati and  in the heart of Sapta Sindhu, the land of seven rivers.
