仁王般若經疏 2.77

2.77

「何以故？一切諸佛是中生、是中滅、是中化，而無生無滅無化；無自無他、第一無二、非化非不化、非相非無相、無來無去，如虛空故。」

"Why is this? All buddhas arise within this, cease within this, and manifest transformations within this; yet there is no arising, no ceasing, and no transformation; there is neither self nor other; it is primary and non-dual, neither transformation nor non-transformation, neither sign nor signless, having neither coming nor going, because it is like empty space."
