In the past, kong-an (koan) practicing meant checking someone's enlightenment. Now we use kong-ans to make our lives correct. . . . You must use kong-ans to take away your opinions. When you take away your opinions, your mind is clear like space, which means from moment to moment you can reflect any situation and respond correctly and meticulously.
To say that 'I will not be free till all humans (or all sentient creatures) are free' is simply to cave in to a kind of nirvana-stupor, to abdicate our humanity, to define ourselves as losers.
