sati verify if ram is vishnu or not at the time when sita was kidnaped by ravan but if u read balkand there sitaji worship parvati before swamvar so that she can have ramji as her husband
actually if u read that prayer
jai jai girraj kishori !!jai mahesh mukh chand chakori
jai gajbadan shadanan mata !!jagat jananin damini duti gata
that mean parvat himalay ki beti aapki jai hoshiv ki mukhrupi chandrama aapki jai ho ganesh aur kartikey ki mata aapki jai ho
so it is clear that she was praying prvati ji as she was himalaya daughter and kartikey and ganesh mother
so if anybody can give me correct info
