Gavin Flood explains artha as "worldly success" without violating dharma (moral responsibility), kama (love) and one's journey towards moksha (spiritual liberation). Flood clarifies that "artha" in ancient Hindu literature, as well as purushartha, is better understood as a goal of Man (not a man). In other words, it is one of the four purposes of human life. The survival and the thriving of humans requires artha – that is, economic activity, wealth and its creation, worldly success, profit, political success and all that is necessary for human existence.
