This is because you are attached to characteristics. There is only this One Mind and not the least bit of dharma that can be attained.

The most important thing is not to maintain the text or form an interpretation of a single [individual] case or a single teaching. Why? There is truly no definitive Dharma that the Tathāgata can preach. In our school we do not discuss these matters (i.e., the doctrines of Buddhism). You should simply understand that we do nothing else but stop the mind. There is no use in thinking about this and that.

[The master] entered the hall and said: Rather than the hundred varieties of erudition, to be without seeking is primary. A religious person is someone who does nothing and is truly without the numerous types of mind. There is also no meaning that can be preached. There’s nothing else, so you may go.
