Manas is electricity and the Light of understanding – the magnetic plasma; all are energy of the Fire ( Breath, heat, light – radiance) .
When embodied, manas is dual, gravitating toward buddhi in its higher aspects and in its lower aspects toward kama. The first is intuitive mind, the second the animal, ratiocinative consciousness, the lower mentality and passions of the personality.
The merging of the fires of matter and the fires of mind results in the energizing of the sumtotal of the atoms of the matter of the body.
The etheric centres have counterparts in the substance of all planes. When kundalini has blended with the pranic fire, the centres become three-dimensional – they reach to the mental substance.
When it blends with mind or solar fire and the two fires are perfectly united, the centres become fourth-dimensional. When it blends with the electric fire of pure Spirit after the third Initiation, they take on two more dimensions.
When in group formation we undergo the great lifting out of the tomb of matter and face for the first time the awesome kundalini fire. This is the experience that awaits all disciples who have purified the lower form, aligned with the soul, and let the principle of love dominate their lives. It is an act or event of Identification:
“Suddenly slow and rhythmic expansions of consciousness are replaced with an explosion of light that literally projects the initiate forward into realms for which there are no adequate descriptions to qualify the stupendous moment wherein one’s whole nature shrinks or contracts before the awesome spectacle of the first aspect of deity.
This event destroys for all times the last vestiges of man’s attachment to the physical world and connects the highest and lowest centers into one burning expression of fire that then becomes lost in pure silence or the darkness of laya that exists prior to all form life. This is the culminating meaning of the seventh ray word of power, ‘the highest and the lowest meet’.”
My additional thoughts (dmm)
Yes, the dimensionality of the centers is readily experienced but not easy to describe. Yet, somehow it is clear that “dimensions” are multiple and accessible, opening onto or within the substances of the planes. I have equated such with the ranges of energy and quality that a person can perceive and interact with. Examples are common to all people, such as patience or creative inspiration, intuition, or ability to manifest. Each has a range of expression, refinement, and power. The unfoldment of the energetic system determines the range or spectrum of vibrancy and utility.
I’ve also understood the dimensional and vortextural capacity and quality of the centers, the flow of fires within the nadis and major channels, the drops of essence (fire/light/emptiness) to be correspondent to the configurations of unfolded petals within any center combined with their geometrization with other center’s and their unfolded petals. In a certain respect, each petal is a vortex, a wormhole, so to speak. It has a particular energetic draw and emission
And, yes, breath is clearly an aspect of both the fires themselves as well as of a “gearing” system whereby different phenomena, unfoldings, and states are supported or produced.
