2.44

He replied: "It is not conjoined with the body, because the body's marks are separated [from it]. Nor is it conjoined with the mind, because the mind's conjunction is like an illusion." [Seng]zhao says: "The marks of the body are separated, so there is no body; the mind is like an illusion, so there is no mind. Since body and mind are both absent, with what could the illness be conjoined? Since there is no conjunction, there is no illness. Because there is no illness, it cannot be seen."
