先生问九川：「于『致知』之说体验如何？」
九川曰：「自觉不同。往时操持常不得个恰好处，此乃是恰好处。」
先生曰：「可知是体来与听讲不同。我初与讲时，知尔只是忽易，未有滋味。只这个要妙再体到深处，日见不同，是无穷尽的。」又曰：「此『致知』二字，真是个千古圣传之秘，见到这里，『百世以俟圣人而不惑』。」
先生问九川：「对『致知』之说体验得怎样？」
九川说：「自觉不同。往时操持常找不到个恰好处，这便是恰好处。」
先生说：「可见体认来的与听讲来的不同。我起初与你讲时，知道你只是轻易看过，没有滋味。只这要妙再体到深处，日日见得不同，是无穷尽的。」又说：「这『致知』二字，真是个千古圣传之秘。见到这里，『百世以俟圣人而不惑』。」
The Master asked me: 'How goes your tasting of extension?'
I said: 'Different, I feel it. Formerly my grip never found the just point — this is the just point.'
He said: 'So tasting differs from hearing. When I first lectured you, I knew you took it lightly, without savor. Carry this subtlety deeper and deeper; daily it shows new — inexhaustible.' He added: 'These two words, extension of knowledge, are truly the secret handed down by sages a thousand ages. Seen to this point, wait a hundred generations for a sage, unconfused.'
