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
ZhuangziWhen the shoe fits, the foot is forgotten. When the belt fits, the belly is forgotten. When the heart is right, "for" and "against" are forgotten. No drives, no compulsions, no needs, no attractions: Then your affairs are under control. You are a free man.
ZhuangziListening stops with the ears, the mind stops with recognition, but spirit is empty and waits on all things.
ZhuangziParaphrased: When Chuang Tzu was about to die, his disciples began planning a splendid funeral. However some disciples expressed concern that given a particular arrangement, birds and kites would eat his remains. Chuang Tzu replied, "Well, above ground I shall be eaten by crows and kites, below it by ants and worms. What do you have against birds?
