Are you referring to the Toh of Kuji In? If so, it does not correspond to the third eye:
The Toh or third chakra focus point is the solar plexus or slightly below.
Visualize a bright light building and glowing brighter in the solar plexus. Observe the color and how it may change with practice.
The Toh Kuji-In enhances your positive relationship with your immediate environment and the universe, resulting in improved harmony and balance.
