Directions: Answer the given question based on the following passage:
Every nation, every culture, has its own approach to the subject of management, as well as to other forms of group life and activity. Today, there are two great nations which are highly specialized in the field of management and have their own philosophies relating to it: one is America and the other is Japan. Not many in India know that their own country has its own philosophy of administration and management that is second to none. And there is a positive sign today that many of our own people are eager to explore it further. Many writers have sprung up expounding this subject, basing their treatment on the great Yoga philosophy and technique of the Bhagvad-Gita.
