I am referring to Buddhist ethics and this has nothing to do with Muslim Sharia law or the re-establishment of caliphates.
If you are genuinely interested in what I am referring to then you can search for pañcasīla (The Five Precepts) which form the foundation of Buddhist ethics/morality/virtue.
> pañcasīla (The Five Precepts) which form the foundation of Buddhist ethics/morality/virtue
Isn't it more accurate to call it an early commonality of Early Budhism than a foundation [1]?
