The earliest evidence of Hinduism comes from the Indus Valley Harrapan sites where in 1931 John Marshall discovered seals of seated male god Pashupati or Pasupati as Lord of the Beasts. Other Hindu Dravidian contents of Hinduism including figures of mother Goddess, Lingam and Yoni, the female and male cosmic powers of creation were also found in the region. They date to the pre-Aryan arrival over 3000 years ago. The concept of male and female, as Shiva and Shakti or Parvati, sometimes both together as one and same in the image of Ardhanarishvara underpins the importance of these forces as powers of creation, procreation, balance of power and emotions.
The resemblance of Pasupati image in this rare post-Gupta gold coin (9th-12th centuries AD) of Pasupati issued by Gangeyadeva, the Kalachuri ruler who was a follower of Hinduism, specifically of the Pasupati sect is striking.
