Everyone is a WORSHIPER!!!
People in the world are entirely engaged in worshiping. Worshiping is not just bounded to God. Different people worship differently. Some people worship wealth while some worship thoughts. Everyone worships according to the interests. Therefore everyone worship differently.
A materialistic person is most likely to be the worshiper of wealth. Such person is busy in accomplishing his aim of making wealth. An intellectual person mostly tend to be the worshiper of knowledge and intellect. Some people worship ideas ad thoughts.
An atheist is also a worshiper in a broader sense. Such person actually worships thoughts and ideas. Therefore everyone is worshiping differently according to the self_interests.
