Here's a colouring page of Ganesha, or Lord Ganesh, one of the Hindu deities. He is the elephant-headed god of wisdom, education and success, and is worshipped at Diwali.
At Diwali there is a day of the celebrations set aside especially for brothers and sisters. Sisters look after their brothers and cook for them, while brothers give their sisters gifts. Here's one of two colouring pages specially created for Bhaija Dooj.
