Shakti and Devi are both terms used in Hinduism to refer to
to the divine feminine energy or power
as well as to the divine feminine being.
However, there is a subtle difference in their meanings and uses.
Shakti generally refers to:
dynamic, creative and transformative energy
which underlies the universe and all aspects of life.
When the reference is to a tattva, shakti is the tattva of the dynamic, creative divine power or energy that creates the universe, manifests immanence and gives substance to the illusion of limitation.
When the word shakti designates a goddess, it is a general term for a very powerful or even archetypally omnipotent female being who, although complete in structure, manifests more or more easily the aspect of energy than the aspect of consciousness. This difference is characteristic of the female state.
In Hinduism, the word Shakti is more often associated with the goddess Durga or Kali, which represents the supreme feminine aspect, terrible and omnipotent.
on the other hand , it is a more general term that is used to refer to any female goddess, including goddesses such as Lakshmi, Saraswati, and Parvati. Devi is sometimes associated with nurturing, compassion and protection.
So Shakti and Devi are two words that can be used to designate the same aspect – – one or the other of the forms of the Supreme Goddess
but Shakti has an additional shade of power, intensity, state or aspect of consciousness of some omnipotent supreme being – Brahmin or God
and Devi clearly means goddess, personal facet of the one Goddess or God-woman.
If the prefix “maha” is mentioned in front then it is about that aspect on a universal level, so Mahashakti is the archetypal Supreme Goddess and Mahadevi is the supreme goddess perfectly free and subject to all female beings in the universe.
Parvati is a goddess in Hinduism considered to be a form of Shakti, the divine feminine energy. She is also known by other names, including Uma, Gauri and Durga. Parvati is the wife of Lord Shiva, one of the most important deities in Hinduism.
Parvati is generally associated with love, fertility, and devotion. She is often depicted as a beautiful goddess with a gentle and nurturing nature. In Hindu mythology, Parvati is said to have undertaken intense penances and austerities to win the love of Shiva, who was initially unaware of her existence. Parvati is also considered the mother of two popular gods, Ganesha and Kartikeya.
Parvati is worshipped by Hindus around the world, especially in India, where she is considered one of the most important and beloved goddesses. She blesses her worshippers with marital harmony, fertility, and prosperity.
