Typically, a group of people or an institution promote a particular cause or multiple causes. For example, a State University promotes the cause of higher education. A political party promotes certain causes to its electoral votes. A church or temple promotes set of values or causes related to scripture or gods in the name of religion. A nation of people come together to promote a specific cause in the name of nationalism etc. So like this in our society we have multiple groups promoting different and varying causes.
In order to address a problem invariably we have to be part or associate with a particular group or institution. So one may ask is the institution more important than the cause or is the cause more important than the institution? Which drives which?
There is a fine line between the institution and cause. If we as the adherents to the institution and cause do not realize the difference, then we will charter into the territory of sectarianism. Personally, sectarianism is the singular problem plaguing the minds of modern civilization. We become more passionate of the institution than the cause itself. Because in the real world, nothing is black and white like the mission statement of an institution which means to address one cause we have to cross party lines. So while we are loyal to an institution, party, caste or nation, it is essential we always remember to put the primary cause or problem in front of everything else. This mental due diligence will help us keep away from sectarian differences.
Perhaps in the real world, this may not be practical all the time but as an individual we can commit to always remind ourselves of why we are here and work with others and their differences to address our root cause.
