Artha; literally means "success."
It is one of the four main religious goals of Hinduism.
The idea is that in addition to following dharma (virture) and kama (pleasure), Hindus should also strive to be successful in the the activities of their lives.
It should be seen in contrast to the goal of moksha, which is to strive for liberation from samsara.
Artha (अर्थ): Wealth, one of the objects of human life, the others being Dharma, (righteous- ness), Kama (satisfaction of desires), Moksha (spiritual salvation)
