artha–wealth, not to be understood solely as material assets, but all kinds of wealth including non-tangibles such as knowledge, friendship and love.
Artha is one of the four purusarthas or “goals of life” the others being dharma, kama and moksa.
dharma–derived from the Sanskrit root dhr meaning to hold up, to carry, to bear, to sustain. The word dharma refers to that which upholds or sustains the universe. Human society, for example, is sustained and upheld by the dharma performed by its members. For example, parents protecting and maintaining children, children being obedient to parents, the king protecting the citizens, are acts of dharma that uphold and sustain society. In this context dharma has the meaning of duty. Dharma also employs the meaning of law, religion, virtue, and ethics. These things uphold and sustain the proper functioning of human society. In philosophy dharma refers to the defining quality of an object. For instance, liquidity is one of the essential dharmas of water; coldness is a dharma of ice. In this case we can think that the existence of an object is sustained or defined by its essential attributes, dharmas.
kama–wish, desire, love. Often used in the sense of sexual desire or love, but not necessarily.
moksa–liberation or freedom of rebirth.
