The global dispersion of Hinduism has ancient roots. Despite the brahmanical proscription against crossing "the black waters," Indian traders whose religious sensibilities would today be called Hindu have plied oceans west and east of the subcontinent for at least two millennia.
Darshan means to see. In Sanskrit, Darshan or Darsana means 'sight', 'vision' or 'glimpse'. It is not seeing a thing or person. It is a glimpse of Divinity. It means to see a Guru or Murti (Image of God) at the place of worship. The effects of Darshan go far beyond mere seeing.
