俱舍論記 8.162

8.162

「次依聖教至業有中有」者，此下依教證有中有，釋後兩句。此即第一引七有經。既言中有，明知別有。

"Next, on the basis of the sacred teaching [...] 'karmic existence, intermediate existence'" onwards proves the existence of intermediate existence based on scripture, explaining the final two lines. This is the first, citing the Sūtra on the Seven Existences (Saptabhava-sūtra). Since it speaks of "intermediate existence," we clearly know that it exists distinctively.
