The Third Eye turns on when the previous five chakras are in balance and open

In ascension, the Winged Serpent/Dragon represents one who has raised their consciousness and liberated themselves from the reincarnation cycle of Samsara. 

The “snake charmer” or “serpent tamer” are metaphors for cultivating the cosmic energy in the Root Chakra, aka Kundalini, and slowly raising it up the spine.

The Third Eye turns on when the previous five chakras are in balance and open. Like a tree, our roots must be strong if we want our branches to grow tall. 

The Kundalini crawls up the chakras from the Root to the Crown. The Third Eye Chakra is like antennas that stretch out and feel higher dimensions.
