Lord Rama Worshipped Lord Shiva Durin His Human Avatar
Lord Vishnu incarnated as Sri Rama in the Treta Yuga. During his life in the jungle, Ravan, the Asura King who ruled Lanka kidnapped Sita- wife of Sri Rama. To get her back and free the people of Lanka from the demon king, Rama reached the seashore(India and Lanka is separated by the sea) with the Vanaras(Army of monkeys) under the leadership of Sugreeva. This place is now the city of Rameswaram in the state of Tamil Nadu in India.
He put down the bowl of water and started doing Poojas for Lord Shiva. His stotras made Lord Shiva contented. He appeared before Ram.
SriRama spoke with devotion.
After being please, Lord Shiva said,
"Rama, you will be prosperous. I'm contented by your devotion."
