Manasa Saras

They climbed on the boat. On one side was River Ganga and on the other side River Sarayu. The boat went fast, and Sage Vishwamitra along with Rama and Lakshmana travelled by this boat. They could hear a loud roaring noise, in the place where the waters of River Ganga and River Sarayu joined. 

As Rama was a young child, he asked Vishwamitra, “O Maharishi! What is the cause of this tumultous noise?” 

Sage Vishwamitra replied, “Surrounding Ayodhya, the holy river Sarayu flows. Do you know what that(river) is? On Mount Kailasa, Brahma by the power of his thought created a lake named Manasa Saras, a branch of this Manasa Saras is only this Sarayu river. As the river Sarayu joins river Ganga here, this loud sound is produced at the confluence.”

Guptahari

Guptahari was the Place in Ayodhya where Lord Vishnu stayed without the knowledge of Asuras who were creating havoc in Bhuloka; Devas and Bhagavan Shankar approached the Lord who assured that He would execute Tapasya for the security of Devas and annihilate them by taking the Avatar of Sri Rama.

Sambheda

Sambheda Tirtha is known as ‘Tilodaki’where the water too has the colour of Black Til and is used for ‘Pitru Tarpanas’ with black Til ie. Sesamum Seeds. Tarpanas on Bhadrapada Krishna Amavasya would help relieve the travails of Pitras and the sins of their seven generations get burnt off with the worship of Narayana.

Chaturdashi

Not far from Brahma Kunda is a Papa Vimochan Tirtha where a Brahmana named Narahari who became a victim of bad company and performed several great sins including cursing the Vedas; but luckily he met a few Sadhus visiting Ayodhya once and along with them performed Snaan, Puja and Daan in the name of Narayana on a special day of Magha Krishna Chaturdasi and all his sins were washed out since he was basically a Brahmana who fell a prey to wrong actions.
