妙法蓮華經玄義 6.153

6.153

For those who formed connections through the distinctive teaching in the past, in the interim they engaged in common tasks, preached the Dharma, and used various instructions to ripen those not yet ripened. The Buddha now appears as a buddha in fragmented [birth and death]. For those who have not attained the Way, there is retributive birth right in this place; descending from the higher realms, there can be volitional and supernormal [births]. Horizontally from other regions, there can be volitional and supernormal [births]. Vertically coming from [the land of] expedients, there are also volitional and supernormal [births]. For those coming vertically from [the land of] true reward, there can be responsive birth: ignorance having been broken beforehand and the root of the dharma-kāya having already been attained, they are able to give rise to a response and enter birth and death. This is different from the previous [teachings] (and so on).
