Shiva and Parvati's Marriage
शिव-पार्वती विवाह
Quick Answer
After Sati's self-immolation, she was reborn as Parvati and performed intense tapasya to win Shiva's love. Despite Kamadeva being burned to ashes for disturbing Shiva's meditation, Parvati's devotion melted the great ascetic's heart and they married on Mahashivratri.
