Core Insight:
According to Osho, the two eyes and the third eye share the same seeing-energy; when it is engaged in the physical eyes you perceive only the material, but when withdrawn it flows through the subtle-body center between the brows, opening perception of the soul and subtle realms. Techniques of steady, unmoving staring make the physical eyes 'stony,' halting their energy flow so it diverts into the third eye and activates it.
