Shakti means force, power or energy in Hinduism & she personifies
the female aspect of God. She is even referred as 'The Divine Mother'.
The goddess symbolizes the active, dynamic principles of feminine power.
As per Shaktism, she is as the Supreme Being. There is a counter view as
well in other Hindu traditions where she has been depicted embodying the
active energy and power of male deities such as Vishnu in Vaishnavism or
Shiva in Shaivism. As we all know that Vishnu's shakti counterpart is
Lakshmi, with Parvati being the female shakti of Shiva.Shakti denotes the eternal and Supreme Power who manifests energy, and substance of everything, and all-pervading. She is connected with & identical to the power of the gods. She, like other goddesses, is the source of the universe. She even represents the violent aspects of Durgha & Kali as well the creative aspects of Shiva.
According to Tantrism philosophy, the Shakti defines the unity of opposites.
