Here are a few quotes that can help us to understand and define the word Fohat:
~~~
“Fohat is ... the dynamic energy of Cosmic Ideation.... [It is] ... the animating principle electrifying every atom into life.” (H.P. Blavatsky,
The Secret Doctrine, vol. I page 16)
“Fohat ... is the personified electric vital power, the transcendental binding Unity of all Cosmic Energies, on the unseen as on the manifested planes, the action of which resembles — on an immense scale — that of a living Force.... On the earthly plane [Fohat's] influence is felt in the magnetic and active force generated by the strong desire of the magnetizer. On the Cosmic, it is present in the constructive power that carries out, in the formation of things — from the planetary system down to the glow-worm and simple daisy....” (H.P. Blavatsky,
The Secret Doctrine, vol. I page 111)
“Some faint idea of the nature of Fohat may be gathered from the appellation ‘Cosmic Electricity’ sometimes applied to it; but to the commonly known properties of electricity must, in this case, be added others, including intelligence.” (H.P. Blavatsky,
The Secret Doctrine, vol. I page 85)
“When the ‘Divine Son’ breaks forth, then Fohat becomes the propelling force, the active Power which causes the ONE to become TWO and THREE — on the Cosmic plane of manifestation. The triple One differentiates into the many, and then Fohat is transformed into that force which brings together the elemental atoms and makes them aggregate and combine.” (H.P. Blavatsky,
The Secret Doctrine, vol. I page 109)
Fohat is the energy of Life, “which manifests in the objective universe” as Electricity. (H.P. Blavatsky,
The Secret Doctrine, vol. I page 137)
