As a teacher unfurls the flag, two little boys raise their hands in salute, their head and shoulders barely above water in one of the many districts flooded across the state.
The photo was first shared on Facebook on Tuesday by Mizanur Rehman, an assistant teacher at Naskara Lower Primary School in Dhubri. By the end of the day, the image had captured the nation's attention and had also been carried by international news websites.
The photo has been shared over a lakh times on Facebook and was part of countless WhatsApp forwards.
"I'm the assistant (sic) teacher at this school, school name...1185 No. Naskara LP school.. under Fakirganj Police station. Dhubri....no need to tell how we are right now, pic will tell all the stories...I did not expect this kind of support....thank you all for sharing this picture," wrote Mizanur Rehman in a caption accompanying the picture.
The story behind the photograph has now been revealed.
According to a state rule, every event at a government school has to be documented with photographs and this photo was taken to be sent to the state education department in Guwahati. The young students in the photograph were chosen because they can swim. As the four sang the national anthem and vande mataram, the remaining students and teachers watched them from higher ground outside the school.
In a subsequent post two days later, Mr Rehman wrote: "I would like to thank all the people of our region, despite of heavy flood, you have not failed to show your true patriotism and love for our great country. This phenomenal success is the reflection of the ever increasing dedication and love for this country."
