教觀綱宗 1.18

1.18

頓有二義：一、頓教部，謂初成道為大根人之所頓說，唯局《華嚴》（凡一代中，直說界外大法，不與三乘共者，如《梵網》、《圓覺》等經，並宜收入此部。是謂以別定通，攝通入別也）；二、頓教相，謂初發心時便成正覺，及性修不二、生佛體同等義，則《方等》、《般若》諸經，悉皆有之。

Sudden has two meanings: First, the sudden teaching division, meaning that when the Buddha first attained the Way, what was suddenly expounded for people of great capacity is restricted only to the Avataṃsaka. (Throughout his lifetime, those teachings that directly expound the great Dharma beyond the realms, not shared with the three vehicles, such as the Brahmajāla and Perfect Enlightenment sūtras, should all be included in this division. This is called using the distinct to define the shared, and subsuming the shared into the distinct.) Second, the sudden teaching characteristic, meaning attaining correct enlightenment at the initial arousal of the mind, the non-duality of nature and practice, and the identity of essence between sentient beings and Buddhas; these meanings are present in all the Vaipulya and Prajñā sūtras.
