One of the things that Hindus do in the River Ganges is to bathe. This is symbolic for them to wash away the wrong things they have done and to feel pure. Think about how it feels when something that was messy is clean or when you have a bath after having got really messy.
Can you find something to clean or tidy (ask a grown up for some ideas if you can’t think of anything). Think about how it feels when something is cleaned. How do you think this compares with how a Hindu might feel after they have bathed in the Ganges?
