yes... "hinduism" but it is not called as 'hinduism' which is a contemporary name... i couldn't find any 'historical' name... historically this is called 'sanatana dharma' meaning - "the law which is"... 'is' as in eternity... without end or begining... may be we can interpret it as "the law of the being"... well i am not good in any language... forgive me if there's any mistake... this is definitely not from my knowledge- i have read in different books and also learnt the same from some 'sivacharyas'... currently i am in search of the meaning for the sankalp mantra which... as this reply says... seems to record the "current" temporal and cosmic location. "current" for the sankalp.
seems like there weren't any religion at that time as the article
