Etymology
From ; literally "a ṛ́ṣi alters a message".

 * "Should this boy come in daytime, devour him in daytime. Should he come in nighttime, devour him in nighttime."

Rathasena met a ṛ́ṣi en route. The ṛ́ṣi, having learnt of the message, secretly reversed the text that the message became:


 * "Should this boy come in daytime, marry him in daytime. Should he come in nighttime, marry him in nighttime."

So the daughter of the ogress married Rathasena.
