Bhadrakalpikasutra is a collection of ancient Hindu teachings about how to live a moral and happy life. It was written over 2,400 years ago and it is still used today by people of the Hindu faith. The teachings are based on the idea that good actions will bring about good results and create a better world. The sutras talk about things like karma (actions having consequences), the power of truth and honesty, the need for education, and how to balance physical and spiritual practices. This ancient advice is still relevant today because it offers helpful guidance on how to live in harmony with yourself, with others, and with the world.
