3.287

譬猶三鳥出網，同適無患之域。無患雖同，而鳥鳥各異。不可以鳥鳥各異，謂無患亦異。又不可以無患既一，而一於眾鳥。然則鳥即無患、無患即鳥，無患豈異？異自鳥耳。

It is just like three birds escaping from a net, all proceeding to a realm free from affliction. Although freedom from affliction is the same, bird and bird are each distinct. One cannot, because bird and bird are each distinct, say that freedom from affliction is also distinct. Nor can one, because freedom from affliction is one, make all the birds one. Thus the bird is identical to freedom from affliction, and freedom from affliction is identical to the bird. How could freedom from affliction be different? The difference comes from the birds themselves.
