Question: ‘Who teaches these words? [1]’
Answer: 'It is as I have been asked.’
Question: 'What does it mean to say that it is as you have been asked?’ Answer: 'If you contemplate [your own] questions, the answers will be understood [thereby] as well.’

At this Yuanmen was silent and he thought everything through once again. Ruli asked: “Why do you not say anything?” Yuanmen answered: “I do not perceive even the most minute bit of anything that can be explained.” At this point [the master] said to Yuanmen: “You would appear to have now perceived the True Principle.”

[1] That is, the master’s (Ruli) instruction, which is primarily in the form of negation.

Pregunta: ¿Quién enseña estas palabras? [1] '
Respuesta: "Es como si yo hubiese preguntado."
Pregunta: "¿Qué significa decir que es como se yo hubiese preguntado?"
Respuesta: "Si contemplas [tus propias] preguntas, con ello tambien se entenderán las respuestas.

Con ésto Yuanmen quedó en silencio y volvió a pensar todo una vez más.
Ruli preguntó: "¿Por qué no dices nada?"
Yuanmeng respondió: ". No percibo incluso el minuto más bit de nada que pueda ser explicado"
En este momento [el maestro] le dice a Yuanmen: "Te parecerá que ahora percibes el Verdadero Principio".

[1] Es decir, la instrucción del maestro (Ruli), es principalmente en la forma de negación.
