Okay little one, the Sri Guru Granth Sahib is a book that Sikhs believe was given to them by their ten gurus who were wise teachers. It's like a really important guidebook for Sikhs, kind of like how some people have a Bible or a Quran.
The book is written in a special language called Gurmukhi which is spoken in India, and it talks about how to live a good life and how to be kind to others. Sikhs believe that the words in this book are very powerful and can help guide them on their spiritual journeys.
Some Sikhs even have a special room in their homes called a Gurdwara where they keep the Sri Guru Granth Sahib and read from it every day. And when they go to the Gurdwara, they show respect by covering their heads, taking off their shoes, and bowing down to the book as a sign of gratitude and reverence.
So, in summary, the Sri Guru Granth Sahib is a really special book for Sikhs that teaches them how to be good people and live a fulfilling life.
