Furthermore, the Samantapāsādikā states: The Buddha said: Nāgas have five situations in which they cannot be free from the nāga body. What are the five? First, when engaging in sexual intercourse: if engaging in intercourse with a nāga, they may remain in nāga body, but if engaging in intercourse with a human, they cannot be free from the nāga body. Second, at the time of taking rebirth, they are not free from the nāga body. Third, at the time of shedding skin. Fourth, when asleep. Fifth, at the time of death. These are the five situations in which they cannot be free from the nāga body.
