The wise traveler leaves his heart at home= this means that, no matter where you are going, you should always go back home, because every place is beautiful, but the most beautiful place is the one that you can call a home, the one where your loved ones are.
Travel broadens the mind= this means, that the more places you visit, the more you find out things about people that live there, their culture, their way of dealing with problems, their lifestyle, and all that knowledge can change your way of thinking, it can make you a better person, a "richer"person.
