Six at the top means:

Going leads to obstructions,
Coming leads to great good fortune.
It furthers one to see the great man.


This refers to a man who has already left the world and its tumult behind him. When the time of obstructions arrives, it might seem that the simplest thing for him to do would be to turn his back upon the world and take refuge in the beyond. But this road is barred to him. He must not seek his own salvation and abandon the world to its adversity. Duty calls him back once more into the turmoil of life. Precisely because of his experience and inner freedom, he is able to create something both great and complete that brings good fortune. And it is favorable to see the great man in alliance with whom one can achieve the work of rescue.
