Dear Aleix
In fact, I do not know their origin, but they were composed to a daily recitation suttas collection for Vietnamese buddhist of Theravada. They're very popular in Vietnam, even you can search them on google
They were already translated to Vietnam. The whole verses are:
Sabbalābhaṃ
bhavissati
Therassa
anubhāvena,
Sabbe hontu
piyaṃ mama
Sīvali ca mahālābhaṃ
Sabbalābhaṃ bhavissati
Therassa anubhāvena,
Sabbe hontu piyaṃ mama
Mama sise ṭhapetvāna,
Mantitena jāyomantaṃ
Ahaṃ vandāmi sabbadā
However, you're right when making question about its origin. Because I also tried to search it by DPR and was unable to reach anything relating to them, except the name Sīvali
Anyway, it's still a chance for me to learn more about Buddhist texts in general
Sincerely yours,
Huynh Trong Khanh

Dear Huynh Trong Khanh,
May I ask where do these verses come from?
