She is said to be the daughter of the Himalayas and a model for the ideal wife. Sometimes called Devi, Parvati is generally seen as a benevolent, nurturing and protective deity.
In one variant of her mythic cycle, Parvati is the reincarnated Sati, who formerly took her own life. At the request of Vishnu she stops the distraught Siva from undertaking his terrible dance of cosmic destruction.
Some regard Parvati as the exemplary shakti. Shakti is a Sanskrit term for female power, sometimes called ‘serpent power’ because it is believed to rise upwards like a serpent through the chakras of the meditating yogi or yogini.
Like many deities, Parvati has a dark side and it would be incomplete to describe her as entirely benevolent.
Several Hindu stories present alternate aspects of Parvati, such as the ferocious, violent aspect as Shakti and related forms. Shakti is pure energy, untamed, unchecked and chaotic. Her wrath crystallizes into a dark, blood-thirsty, tangled-hair Goddess with an open mouth and a drooping tongue. This goddess is usually identified as the terrible Mahakali or Kali (time). In Linga Purana, Parvati metamorphoses into Kali, on the request of Shiva, to destroy a female asura (demoness) Daruka. Even after destroying the demoness, Kali’s wrath could not be controlled. To lower Kali’s rage, Shiva appeared as a crying baby. The cries of the baby raised the maternal instinct of Kali who resorts back to her benign form as Parvati. In Skanda Purana, Parvati assumes the form of a warrior-goddess and defeats a demon called Durg.¹
Shakti also refers to a general principle of creative, cosmic energy. Some believe that when this energy is personified it takes the form of a goddess, such as Parvati or Krishna’s playmate, Radha. Others, of course, say these goddesses are real, in themselves, and not mere personifications of some general principle.
In one Purana (a Hindu religious text), Parvati is the mother of all other goddesses, universally worshiped with many forms and names. Her appearance and form depends on her overall cosmic purpose or, as Wikipedia suggests, on her “mood.”²
Personally, I think this Wikipedia take is too small a perspective considering the depth and breadth of Hindu myth, philosophy and religion.
