不空成就如来

From Middle Chinese 不空成就如來 (pjuw khuwng dzyeng dzjuwH njo loj). Compare modern Mandarin 不空成就佛 (bùkōng chéngjiù fō), exchanging 如來 / 如来 (rúlái) for roughly synonymous 佛 (fō).

The Middle Chinese term itself is a compound of 不空成就 + 如來 (nyo loj):

• 不空成就 is a translation of Sanskrit अमोघसिद्धि (amoghasiddhi), the name of this entity, and a compound of अमोघ (amogha, “not in vain”) + सिद्धि (siddhi, “perfection; accomplishment, attainment; success”).
• 如來 (nyo loj) is an abbreviation of either 如去如來 or 如來如去 (“coming from suchness, going back into suchness”), translations of Sanskrit तथागत (tathāgata, “coming from suchness, going back into suchness; thus coming, thus going”, exact meaning uncertain, see Tathāgata on Wikipedia.Wikipedia ).^[1][2]
