In the past travel was considered an essential part of education. Poets and writers realised the value of travel and went out to other countries in search of knowledge. A man's education was not completed until he had visited foreign lands. That travel broadens the mind cannot be denied. Those who remain within the confines of their homes are cut off from the outside world. As a result, they develop a narrow outlook on life. But those who travel come into contact with various types of people whose ways of life are completely different from theirs. They see things with their own eyes and have a better understanding of the affairs of the world.The impressions that they receive while they travel remain fresh in their minds for many years, and all false impressions and ideas are removed from their minds.
