Those who come to realize thusness* do not see birth-and-death and do not see nirvana. Birth-and-death and nirvana are equal and without distinction.
~The Avatamsaka Sutra
* Thusness in the East Asian Mahayana tradition is seen as representing the base reality and can be used to terminate the use of words. Thusness is of itself endowed with sublime attributes. It manifests the highest wisdom which shines throughout the world, it has true knowledge and a mind resting simply in its own being. It is eternal, blissful, its own self-being and the purest simplicity; it is invigorating, immutable, free. Because it possesses all these attributes and is deprived of nothing.
