From the book "Natural Great Perfection" By Nyoshul Khenpo
"Buddhahood, the awakened state, is the very nature of all sentient beings without exception. There are many spiritual masters who have recognized this inexpressible reality. Even in this world, and even now there are said to be many hidden or discrete enlightened ones who are not generally recognized as great spiritual sages or saints, but have deeply tasted the fruit of enlightenment and are living it. Perhaps they are anonymously doing their good works here among us right now!
This infinite vast expanse, this enlightenment is one's own inconceivable nature. Who can say who has realized it and who hasn't? There are so many beings who have tasted it.
In some beings, we can see it in their behavior, in their countenance. This true nature is so vast and inconceivable, even some birds and animals and beings in other unseen dimensions can be said to have realized it. Who of us can say who is excluded from it?
It is very important to cultivate and practice a sacred outlook, pure vision: recognizing everything as perfect by nature, not seeing some beings as lower and deluded and some beings as higher, more evolved, enlightened; perceiving all beings as part of that boundless mandala of the Innate Great Perfection."
