All human beings live four cells as per empirical observations of one scholar: First are natural restrains. Humans are bounded by natural environment, seasons, atmospheric conditions, other living beings, calamities and every thing else present in the eco system. Second confine to humans is history — the chronology of the past. It is so very difficult to get rid of the past. Third is society. Humans simply cannot live oblivious of the societal traditions and customs. It is not possible to live alone nor is it workable to violate folks, mores and norms of society while living as its part.
And last is own self. Envy, love, anger, joy, desire, sex, prejudice, self-indulgence and fears that compel humans to restrict behind the walls of own self.
How can one throw away all these yokes and truly set free. Science can take control of nature. Understanding of philosophy can free the humans from burdens of what went before. Knowledge of social sciences can steer them safely through the society. But getting away from self is the most daunting of the tasks. For that one needs altruism. And that can only be attained through passion for others. Can you suggest any other way?
