Chinese Philosopher, Third Founding Teacher of the Flower Garland School of Buddhism, said to have authored over a hundred volumes of essays and commentaries
The universal of an atom containing emptiness and existence. This means that the atom has no intrinsic nature, so it is empty; yet its illusory characteristics are evident, so it is existent. Indeed, because illusory form has no essence, it must be no different from emptiness, and real emptiness contains qualities permeating to the surface of existence. Seeing that form is empty produces great wisdom and not dwelling in birth-and-death; seeing that emptiness is form produces great compassion and not dwelling in nirvana. When form and emptiness are nondual, compassion and wisdom are not different; only this is true seeing.
