The mind remains undetermined in the great Void. Here the highest knowledge is unbounded. That which gives things their thusness cannot be delimited by things. So when we speak of 'limits', we remain confined to limited things. The limit of the unlimited is called 'fullness.' The limitlessness of the limited is called 'emptiness.' Tao is the source of both. But it is itself neither fullness nor emptiness
ZhuangziThe saying goes, 'The sage rests, truly rests and is at ease.' This manifests itself in calmness and detachment, so that worries and distress cannot affect him, nothing unpleasant can disturb him, his Virtue is complete and his spirit is not stirred up.
ZhuangziNow, when ordinary people attempt to find happiness, I am not sure whether the happiness is really happiness or not. I study what ordinary people do to find happiness, what they struggle for, rushing about apparently unable to stop.
ZhuangziHow do I know that loving life is not a delusion? How do I know that in hating death I am not like a man who, having left home in his youth, has forgotten the way back?...someday there will be a great awakening when we know that this is all a great dream. Yet the stupid believe that they are awake, busily and brightly assuming they understand things, calling this man ruler, and that man a herdsman- how dense!
