2.19

法記云：七種苦諦者，七種生死也，謂分段有三、變易有四。分段三者，是三界也。變易四者，一方便生死、二因緣生死、三有有生死、四無有生死。

Fa's Record says: The seven kinds of the truth of suffering are the seven kinds of birth-and-death; namely, there are three of apportioned [birth-and-death] and four of inconceivable transformation [birth-and-death]. The three of apportioned [birth-and-death] are the three realms. The four of inconceivable transformation [birth-and-death] are: first, birth-and-death through upāya; second, birth-and-death through causes and conditions; third, birth-and-death through possessing existence; fourth, birth-and-death through non-existence.
