If it is reached for, it cannot be grasped. If it is listened for, it cannot be heard. If it is looked for, it cannot be seen. No it is not a relative who owes you money, but the mighty Dao. Everywhere, but nowhere. Within everything, but without form or shape. This ultimate escape artist can never be captured. A Houdini that escapes every time from that which seeks to contain it. The true Dao master who can walk through walls that cannot hold him. The escapee that no bloodhound can track. It is the butterfly that continually escapes from any net.
