Meaning and elaboration
Meaning: The Supreme Power and living Energy that pervades all existence, the Divine Feminine itself.
Elaboration
Shaktih is the Sanskrit word for "Power," "Force," "Energy," or "Capability." In Hindu philosophy, and especially in Shaktism, it does not mean power in a general sense. It points to the Supreme Power itself: the dynamic, creative aspect of the Divine, the primordial cosmic energy that underlies all existence.
The Divine Feminine Principle Shaktih is synonymous with the Divine Feminine, the Great Goddess, who is ultimately Mahakali. She is the active principle of the cosmos, the kinetic force that brings movement and form to the still, transcendent consciousness represented by Shiva. Without Shakti, Shiva is inert; without Shiva, Shakti remains unmanifest. They are two inseparable aspects of the one ultimate reality.
Pervasive Cosmic Energy Shaktih is not merely a deity but the foundational energy, Prana Shakti, that animates and enlivens everything. From the subtle vibration of a thought to the vast forces that hold galaxies together, from the creation of universes (Srishti) to their sustenance (Sthiti) and eventual dissolution (Samhara), it is Shaktih that carries out all these actions. She is woven into the very fabric of reality, present in every atom and every being.
The Source of All Manifestation As the Supreme Power, Shaktih is the source from which all forms, names, qualities, and experiences arise. She is the creative power of Brahma, the sustaining power of Vishnu, and the transformative power of Shiva. All other gods and goddesses are understood as manifestations or aspects of this one supreme Shaktih. Devotion to Shaktih is the recognition of this all-pervading divine energy within oneself and throughout the universe.
