The term 'Be Rootless' can be interpreted as a call to action to explore and wander without being tied down to one place. This is reflected in the two crossword solutions, ROAM and ROVE, which both mean to travel around without a fixed destination. ROAM is defined as to wander or move about aimlessly, while ROVE is defined as to wander from place to place without any specific purpose. Together, these two words suggest that one should be open to new experiences and not be confined to one place.
