Heliocentric = centered around Helios, Apollo, the Sun or Son of God, Chokmah, Christ.
Geocentric = centered around Gaia, the earth, Malkuth, or physicality.
Gnosticism is heliocentric, focused on the development of Christ, the Sun or Son of Man, within our body, the earth.
According to ancient masters, the earth was the center of the microcosmic universe (not the macrocosmos!) due to the fact that we need our physicality to self-realize and perform the great work.
For thirty years I sought God. But when I looked carefully I found that in reality God was the seeker and I the sought. -Bayazid al-Bastami
