What virtues should a person inculcate within himself to develop a universal outlook?

Objective thinking arouses universal approach. The more objectively a person thinks the more universal he becomes. Normally people think subjectively and are not able to think keeping the entire humanity in mind. They restrict themselves to their family, society and community. Each person therefore must introspect and get to know whether he has a self-centered or a universal approach. A man can get to know this himself and can also work on it himself.
