While dying, Sati asked a boon of Sri Hari that she might remain devoted to the feet of Shiva in all successive births,
That is Why She was Reborn as Parvati, daughter of mountain in the house of Himachala,
The presiding deity of Himalaya mountain,
Ever since Parvati was born in the house of Himalaya the mountain became an abode of all blessings and prosperity,
May Lord Bless all,
Thanks Please
