Parvati-maataa's basic nimmitt has been to protect its bhakto
and the shrusti so they can serve Brhmah. Here is some
of her krupa to her bhakto:
1. Arjun of Paandavo brothers in Mahaabhaarat
was constantly guarded by Paarvatti-devi during Paandavo's 13 year
van-vaas (exile in forest).
2. Krishna-bhagvaan during his avatar once
propitiated Paarvatiji and obtained boons to have sixteen thousand wives;
Krishna to have a handsome form, get affection from his relatives and
have prosperity to offer food to seven thousand atithi (guests)
3. Paarvati-devi expounded to Gangaa-devi the
sva-dharma of women during their various aashramo in life which
then became the standard for all women.
WARNING: It is adhaarmic and
dangerous for one to offend any devataao and especially Paarvatti-devi.
The devo can never bear sons by their own wives because of a curse of Paarvati-devi
on them. The curse resulted from anger in Paarvati-devi when devo
asked Shiv-bhagvan to not bear a son of Paarvati-devi because the
whole world would not be able to support a son born of them because of the
shakti that the son would get from Shiv-bhagvaan. And Shiv-dev
agreed to do so.
