In the Tantric tradition, Shakti is not metaphor. She is real. She is the energy that moves through all things — the force that makes the sun rise, the river flow, the seed break open. Without Shakti, even Shiva is inert.
Shakti is creative power in its purest form. She is not gentle. She is Durga on the battlefield and Kali at the threshold of transformation. To awaken Shakti in yourself is to meet the part of you that does not ask for permission.
