Lokāyatika = འཇིག་རྟེན་རྒྱང་འཕེན་པ།

Although Tibetan rendering of Lokāyatika is often spelled as ’Jig-rten-rgyang-phan-pa (e.g. TSD, s.v. mi bsten), the correct spelling seems to be ’Jig-rten-rgyang-’phen-pa (as recorded, for example, in the Tshig mdzod chen mo (s.v. ’jig rten rgyang ’phen pa). This is because Tibetan translators seem to have taken for granted that āyatika in lokāyatika is derived from āyati, that is, in the sense of “stretching,” “extending,” or “extension” (MW, s.v. āyati). Thus ’jig rten rgyang ’phen pa is to be probably interpreted as “one whose [philosophical] extensional scope (rgyang ’phen) is [confined to this material] world (’jig rten).” That is, why a lokāyatika can be called a “materialist.”
