The big idea

In Guru Nanak Dev Ji's time, people were kept apart by caste, and some were called “untouchable.” Bhai Mardana, Guru Ji's lifelong companion, is treated this way in Haridwar. Guru Nanak Dev Ji answers that truth, good actions and remembering the Creator make a person pure, not rituals. The equality of every human being is at the heart of Sikhi, and this is a gentle first look at it.

A Story from the Travels of Guru Nanak Dev Ji

Guru Nanak Dev Ji’s Travels

Long, long ago, there lived Guru Nanak Dev Ji. He was always smiling and kind. He wanted people to know how to live truthfully and be good human beings.

So, with His friend Bhai Mardana, He began traveling to many places. Everywhere He went, people loved His words and became His students, called Sikhs.

Haridwar

On His first journey, Guru Nanak Dev Ji came to the famous city of Haridwar.

He and Bhai Mardana camped by the river Ganges for the night. It was the festival of Vaisakhi, and many people had come to celebrate.

The Sadhu by the River

Near their camp, a Vaishnav sadhu, a wandering holy man, was staying. He pretended to be very holy and wise. From far and wide, people came to meet him. They thought he was a true teacher.

But Guru Nanak Dev Ji could see that this man was only pretending. He decided to camp close by to show everyone the truth.

The Morning Ritual

The next morning, the sadhu took a bath in the river. Then he got ready to cook his breakfast. He wanted to show everyone how pure and holy he was.

First, he cleaned his cooking area with cow dung. Then he washed his wood sticks in water. He drew special lines around his cooking place to keep it “pure.” Finally, he started a fire with the wood.

Guru Nanak Dev Ji watched quietly. He could see that the man was only worried about outside cleanliness. But what about the inside of his heart?

The Test

Guru Nanak Dev Ji sent His friend Bhai Mardana to ask for some fire. “Please go and get some fire from the sadhu,” said Guru Nanak Dev Ji.

When Bhai Mardana walked toward the cooking area, something terrible happened. The sadhu saw him coming and became very angry. He started shouting loudly.

“You have made my cooking place dirty!” he yelled. “Your shadow fell on my pure area!” He picked up a burning stick and chased after Bhai Mardana.

Bhai Mardana ran back to Guru Nanak Dev Ji, and the angry sadhu followed.

The Angry Words

“Why are you so angry?” asked Guru Nanak Dev Ji calmly. “I only asked for some fire.”

The sadhu was still very mad.

“This man is from a lower caste!” he shouted. “He is untouchable! His shadow made everything dirty. Now my whole life is ruined!”

Guru Nanak Dev Ji asked, “How can this happen? Bhai Mardana is also a human being, just like you.”

“No!” said the sadhu. “He is not human. He is untouchable!”

Guru Nanak Dev Ji’s Teaching

Guru Nanak Dev Ji shook His head sadly. “You are wrong,” He said gently.

“The Creator cannot be fooled by what we see on the outside. The Creator lives in every human heart.”

“If your heart is filled with hate, anger, and cruelty, then the Creator will not want to live there. See the Creator in all people. Do not hate someone because of their caste. Hate only bad actions, not people.”

The Crowd Gathers

By now, many people had heard the shouting. They came running to see what was happening. The sadhu kept yelling about how his pure life was ruined.

But Guru Nanak Dev Ji had something important to say. He sang a beautiful hymn in a clear, strong voice:

“If your heart has lies, meanness, bad talk about others, and angry tricks, then what good are the special lines you draw around your cooking place?

These four bad things are sitting right there with you! Instead, make truth your way of life. Make good actions, your special lines. Make saying the Creator’s Name, your way of getting clean.

Those who stay away from doing wrong things are loved by the Creator.”

The Real Lesson

After Guru Nanak Dev Ji finished singing, everyone gathered around to listen. His words made people think about what was really important.

“Stay away from lies, cruelty, saying bad things about others, and anger,” taught Guru Nanak Dev Ji.

“Instead, live a truthful life. Do good deeds. See the Creator in all people.”

A New Beginning

The sadhu listened carefully to every word. For the first time, he looked inside his own heart. He saw that it was filled with hate and anger. How could he call himself pure when his heart was so dirty? He felt very sorry for his actions. He realized that Guru Nanak Dev Ji was right. What mattered was not the outside, but the inside.

The sadhu stepped forward and asked Guru Nanak Dev Ji to guide him. He promised never to treat people badly because of their caste again. From that day, he became a true student of Guru Nanak Dev Ji, dedicating himself to living with honesty, kindness and helping others.

By serving his community and treating everyone equally, he finally found true happiness.

About the Historical Context

This story comes from Guru Nanak Dev Ji’s travels during the festival of Vaisakhi in Haridwar. For more than 20 years, Guru Nanak Dev Ji went on four long journeys to spread His message of truth and kindness.

Guru Nanak Dev Ji’s message was simple but powerful: All people are equal in the Creator’s eyes. We should judge people by their actions, not by their caste, color, or social status. True purity comes from having a kind and honest heart, not from following outside rituals.

The teaching Guru Nanak Dev Ji gave that day is in His Bani in Sri Guru Granth Sahib Ji (Ang 91). It reminds us that what really matters is how we treat others and the goodness in our hearts.
