Hindus believe that even a glimpse of an image filled with the spirit of the god or saint facilitates a direct visual communication (darshan) with the deity, which will bring blessings to the worshiper. Darshan is a reciprocal act between the worshiper and the deity. Not only does the devotee "see" the deity, but the deity is understood to "see" the worshiper. For this reason, Hindu images often have strikingly large eyes to facilitate this exchange of glances between devotee and deity.
