Sabhaggato vā parisaggato vā
ekassa veko na musā bhaṇeyya.
Na bhāṇaye bhaṇataṃ nānujaññā.
Sabbaṃ abhūtaṃ parivajjayeyya.
Having entered a royal court or a company of people
one should not speak lies.
One should not speak lies (oneself) nor incite others to do so.
One should completely avoid falsehood.
