helping others is helping Brahman, as all living things have an atman, or piece of Brahman, within them. Selfless charitable acts are seen as examples of Karma yoga.
Dana means
giving and sewa means selfless service
The concept of charity in Hinduism is about
helping others without expecting something in return and because it is the right thing to do.
Hindus practise an important concept called ahimsa, which means not harming or killing anything living. Therefore, helping to protect the environment and looking after other people and animals are very important to Hindus.
