Subhuti asked the Buddha: "The highest, most awakened mind that you have attained - is that mind the unattainable?"

"Yes, Subhuti. With regard to that highest and most awakened mind, I have not attained anything. That mind is everywhere equally. It cannot be attained or grasped, but it can be realised. It is realised through the practice of all good actions when they are done in the spirit of no self and no object of self."

-- The Buddha, Prajnaparamita
