The Vajra Prajna Paramita Sutra, p159-160After the Buddha had said that living beings were not living beings and not not living beings, Subhūti asked, “In attaining the unsurpassed, proper and equal, right enlightenment, the one resultant dharma of Buddhahood, there is not even the slightest dharma to be attained. Therefore it is called Anuttara-samyak-saṃbodhi.” That is merely a false name, nothing more. There is no actual substance which one can point to and say, “That is Anuttara-samyak-saṃbodhi.” Why is there not even the smallest dharma which can be attained? The principle was discussed before: if you want to know if something is attainable, you first must know if it has been lost. If it was certain that Anuttara-samyak-saṃbodhi had been lost, then you could retrieve it. But basically you have not lost it. It is what you have always had your basic nature. “In your clothing is a priceless gem, do not further seek outside.” Do not go outside in search of anything. The priceless gem is within your clothing. Cut open your clothing and you will see it.
Anuttara-samyak-saṃbodhi, the unsurpassed, proper and equal, right enlightenment, is a special name for the perfect, full Buddha-fruit. Your Buddha-fruit is certainly not something that can be attained from outside. That which is called Anuttara-samyak-saṃbodhi also does not come from outside. It is what you have always had: your inherent family treasure. The riches are within your own household. If you turn away and seek outside you will be abandoning what you have had all along. You will not find anything that way.
