One of the holiest Hindu festivals, Maha Shivratri, commemorates Lord Shiva and Maa Parvati's marriage and many other cosmic events related to him. According to Hindu mythology, Lord Shiva married Maa Shakti, his divine consort, for a second time on this night. It is in celebration of their divine union that the day is celebrated as 'The Night of Lord Shiva'. While Lord Shiva signifies Purusha - which is mindfulness, Maa Parvati signifies Prakriti - which is nature. The union of this consciousness and energy promotes creation.
