1. Catumahārāja Sutta, v.l. Rāja Sutta, Lokānuvicarana Sutta.–
On the eighth day of the lunar fortnight, the ministers of the Four Great Kings visit the earth, on the fourteenth day their sons, on the fifteenth day the kings themselves. They report what they find at the assembly of the gods in Sudhammā hall and rejoice if men have done good, sorrowing if they have done evil. A.i.142f.
“The person who would be like me should observe the uposatha complete in the eight factors, on the fourteenth, fifteenth, and eighth day of the fortnight, and during special fortnights.”
In this discourse, the Buddha tells the monks that the verse is not well recited because Sakka is not free from birth, aging, and death. He is not free from sorrow, lamentation, pain, sorrow, and despair.
If an Arahant were to recite the verse, it would be well recited. (A.i.144)
