Each of us needs to be acknowledged for what we can contribute to society without compromising the individual identity.
Artha means "achievement" of goals. More specially it relates to the acquisition of valuable objects and so could be referred to as "wealth". Each of us should possess necessary wealth to function happily in life.
Kama literally means "desire" and refers to our need for emotional and sensory happiness in life. As such we call it "enjoyment". All that we do in life should be enjoyable and should not cause pain to ourselves or to others.
Moksha means "liberation or freedom" and relates to our need for spiritual growth, including transcendence of three lower values. It is our power to distinguish between what is good and what is bad. We all must seek to go beyond who we are until we become one with all.
