John Donne said this quote

He that asks me what heaven is, means not to hear me, but to silence me; He knows I cannot tell him; when I meet him there, I shall be able to tell him, and then he will be as able to tell me; yet then we shall be but able to tell one another, this, this that we enjoy is heaven, but the tongues of angels, the tongues of glorified saints, shall not be able to express what that heaven is; for, even in heaven our faculties shall be finite.
