Imagine a World Without Money
Picture this: You are a farmer. You grow rice. But you need clothes. The tailor wants vegetables, not rice. The vegetable seller wants pottery. The potter wants... maybe rice?
This is called barter—trading goods directly for other goods. It sounds simple but creates a big problem: you need to find someone who has exactly what you want AND wants exactly what you have.
Economists call this the "double coincidence of wants." In plain English: bartering is hard because matching needs is difficult.
The Invention That Changed Everything
Humans solved this problem thousands of years ago. Instead of trading goods directly, they invented something to stand in the middle—something everyone would accept.
Different societies used different things:
- •Cowrie shells in India and Africa
- •Salt in ancient Rome (that is where the word "salary" comes from)
- •Tea bricks in China and Tibet
- •Gold and silver coins across the world
Indian merchants were pioneers. Punch-marked silver coins appeared in the Gangetic plains around 600 BCE—some of the earliest coins in the world. Tamil traders carried these along routes stretching from Rome to Indonesia.
The Three Jobs of Money
Today, money does three important jobs:
1. A Medium of Exchange
Money lets you trade easily. You sell your work for money, then use that money to buy what you need. No more finding someone who wants exactly what you have.
2. A Store of Value
You cannot save a hundred eggs—they will rot. But you can save money. Money lets you store your work for later use. A rice farmer can save money in good years and use it in bad years.
3. A Unit of Account
Money gives us a common way to measure value. Is a cow worth more than ten goats? Instead of guessing, we can say: a cow is worth 50,000 rupees, a goat is worth 5,000 rupees. Now comparison is easy.
From Coins to Digital Digits
Money has evolved:
- •Commodity money: Valuable things like gold and silver coins
- •Paper money: Notes backed by a promise from the government
- •Digital money: Numbers in a bank computer—most money today
Here is something surprising: most money is not physical.When you pay with UPI or a bank transfer, no coins or notes move. Just numbers change from one account to another.
In fact, over 90% of money in the world exists only as digital records. The notes and coins in your wallet are just a small fraction.
Ancient Wisdom: Chanakya on Money
Over 2,300 years ago, Chanakya wrote about money in the Arthashastra. His insights still apply today:
"Wealth will slip away from the foolish person who considers it as obtained only for personal enjoyment."
In modern terms: Money is a tool. If you see it only as something to spend on yourself, you will lose it. The wise understand that money should be managed, grown, and used purposefully.
"Artha (wealth) is the chief, for dharma and kama depend on it."
In modern terms: Money matters because it enables everything else. You cannot do good in the world (dharma) or enjoy life (kama) without resources. There is nothing shameful about building wealth—it is the foundation of a meaningful life.

Reflection Question
Think about the last time you paid for something. Did you use cash, card, or a digital app? What were you really exchanging—and what was the other person really receiving?
There is no right answer. The point is to notice what money actually does in your daily life.
