"Be like a servant waiting for the return of the master," says Jesus. The servant does not know at what hour the master is going to come. So he stays awake, alert, poised, still, lest he miss the master's arrival. In another parable, Jesus speaks of the five careless (unconscious) women who do not have enough oil (consciousness) to keep their lamps burning (stay present) and so miss the bridegroom (the Now) and don't get to the wedding feast (enlightenment). These five stand in contrast to the five wise women who have enough oil (stay conscious).
— Eckhart Tolle
