Darshan is a Sanskrit Hindu term meaning sight or a glimpse of the divine. We could have a "darshan" of the deity in the temple (at the gross level) or have a "darshan" in that inward eye of a light or awareness (at a subtle plane). Sudarshan means a glimpse of the "self".
In India people will travel hundreds of kilometres for the darshan, the look, of a holy man or woman because this look is believed to confer blessings. Conversely, looks of anger or envy are widely feared.
Darshan or Drshn means Seeing, derived from drush, to see. To see with reverence and devotion. The term is used specifically for beholding highly revered people with the intention of inwardly contacting and receiving their grace and blessings. "By doing darshan properly a devotee develops affection for God, and God develops affection for that devotee."
In Indian culture, the touching of the feet (pranaam or charansparsh) is a show of respect and it is often an integral part of darshan. Children do touch the feet of their family elders while people of all ages will bend to touch the feet of a great guru or the icon of a Hindu demigod (angel) or a form of God (such as Ram or Krishna).
Vedanta darshan is also the philosophy of life as revealed in the Upanishads.
