The yogic sages—especially in the Hindu and Buddhist branches of Tantra—anticipated quantum physics by claiming that a subtle vibratory energy is the substratum of everything we know. Unlike physicists, however, yogic seers experience this energy not simply as a neutral vibration but as the expression of the divine feminine power, called shakti. Reality, the tradition says, is shakti's dance, which takes its form as our body, our thoughts, our perceptions, and also the physical world.
The Hindu traditions are comfortable with the idea that absolute reality, while formless, also manifests itself as divine entities. So shakti, the formless source of everything, is understood to take on forms: goddesses, or personifications of the energies that make up the world and our consciousness. Whether or not we "believe" in goddesses, contemplating them can help us become intimate with universal forces that otherwise can seem vast and impersonal. Paradoxically, goddess practice can also reveal how the forces that move our thoughts and emotions are ultimately not personal but are archetypal energies we all share.
