Dharma is a key concept with multiple meanings in the Indian religions — Hinduism, Buddhism, Sikhism and Jainism. There is no single word translation for dharma in Western languages. Usually it means virtuous, proper, moral life.
In Hinduism, dharma signifies behaviors that are considered to be in accord with rta, the order that makes life and universe possible, and includes duties, rights, laws, conduct, virtues and ‘‘right way of living’’.

The importance of dharma to Indian sentiments is illustrated by India’s decision in 1947 to include the Ashoka Chakra, a depiction of the dharmachakra ( the “wheel of dharma”), as the central motif on its flag.
