The subpersonal chakras connect one to the energies of the Earth and nature, just as the transpersonal chakras connect us to higher/spiritual energies. They are five in number and the instructions for opening them follow.
The first subpersonal chakra is a few inches below the feet. It connects one to natural energies and helps him practically implement his personal Wyrd [Destiny]. It is a dark, brownish grey, and its inner cortex is a light brownish grey. The names Belial or Hekate can be used as the words of power for this chakra.
The second subpersonal chakra is slightly below the first. It connects one with their personal community and tribe. It is transparent, except for its inner cortex which is white. The names Nahema (name for Na’amah) or Basileia (name for Hecate) can be used for this chakra.
The third subpersonal chakra connects one with feminine energies. It is transparent, except for its inner cortex which is white. The words Lilith Savta [Lilith the Elder] or Trevia [name for Hekate] can be used for this chakra.
The fourth subpersonal chakra links one to ancient telluric energies. It is transparent, except for its inner cortex which is white. The names Belial or Enodia (Name for Hekate) are useful.
The fifth subpersonal chakra connects one to the Earth Goddess. It is a goldish bronze with an inner cortex of goldish yellow. The names Nahema or Enodia are useful here.
If one intends to meditate on all five chakras at once, the names Nahema or Hekate Enodia should be used as the word of power.
Update: I now use the name of the demon Lepaca for opening any given chakra and advise others to do the same For my article regarding Lepaca, follow the link below:
Another Update: My word of power “Phaos Abussos” [Light of the Underworld] empowers the transpersonal chakras, spinal chakras, and subpersonal chakras simultaneously with demonic energy.
