the power to know it but not knowing, the power to assimilate that but not assimilating–that is śakti, and that śakti diverts in[to] the internal vacuum of God consciousness
This passage defines śakti (akti) as latent power that, even in its unfulfilled state, redirects consciousness toward divine absorption, making the unrealized energy itself the vehicle of liberation.
