Sanathana Dharma, or Hinduism, means the Religion Eternal. It is one of the most ancient religions. Down the ages it has accumulated countless spiritual treasures. Innumerable saints, sages, prophets and incarnations have appeared and nurtured it and have been nurtured by it. There is no religious idea anywhere in the world for which one cannot find a parallel in Hinduism.
Religion is purely a human phenomenon.
Hinduism is an Indian religion and is therefore also known as Bharatha Dharma. This excludes the other three semantic religions, namely Judaism, Christianity and Islam. The general Indian Religion or Bharatha Dharma holds that the world is an order or cosmos. The world order is Dharma which is that by which the universe is upheld. Dharma means Righteousness.
