Power through Dominion is achieved by attaining personage of immortal Truth.
For example, YHVH is not Monad but he channels the aspect of the immortal Truth of Monad to achieve dominion.
The same is true of all energetic channeling and evocation. The energetic dimensions outlined by Bardon are not interfaced by projecting outward but by channeling the relevant Truth into manifestation in one's own soul (personage).
