Nothing Attained, Nothing Taught

And again Bhagavat spoke thus to the venerable Subhûti: 'What do you think, O Subhûti, is there anything (dharma) that was known by the Tathâgata under the name of the highest perfect knowledge, or anything that was taught by the Tathâgata?'

After these words, the venerable Subhûti spoke thus to Bhagavat: 'As I, O Bhagavat, understand the meaning of the preaching of the Bhagavat, there is nothing that was known by the Tathâgata under the name of the highest perfect knowledge, nor is there anything that is taught by the Tathâgata.

And why?

Because that thing which was known or taught by the Tathâgata is incomprehensible and inexpressible.

It is neither a thing nor no-thing.

And why?

Because the holy persons are of imperfect power.'
