The legend of this temple stretches beyond the period of the Ramayana (
Treta Yuga). It is believed that Shri
Rama along with his wife
Sita, brother
Lakshmana and the whole vaanara sena, on their way back to
Ayodhya after the victory over
Ravana, visited Sasthamcotta to pay their reverence to Shri Dharma Sastha. Shri Rama offered
pithru tharpan on the banks of the Sasthamcotta Lake, the water of which is supposed to be identical to
Surya Raga Theertha of Manasa Sarovar. Lord Rama then deputed the chief architect of his vanara (monkey) team,
Neelan to serve his host. Neelan is believed to be the predecessor of the prevailing monkey clan in this temple. ==Festivals==
