Nigambodh Ghat

It is believed that it was on this ghat during the Mahabharat era, Lord Brahma, Hindu God of Creation, had bathed and recovered his lost memory and sacred books and hence the name Nigambodh Ghat, literally realization of knowledge.

Prayag to Kanchi

Lord Brahma was born from the Nabhikamala of Sri Hari. Brahma was given the duty of creation which he performs for a long time. Suddenly Brahma was unable to have the darshan of Sri Hari. Due to this he performed tapas in various punya teerthas to obtain the darshan of Sri Hari. The notable kestra was Prayaga Kestra. Brahma performed 100 Aswamedha Yaga in Prayaga kestra (by which it was named Prayaga)

where he received a Ashareera Vani saying that he has to perform 1000 Aswamedha Yaga to get the darshan of Sri Hari. Brahma pleaded and requested for a darshan as soon as possible and doing 1000 aswamedha would take a long time. Ashareera vani gave the details of Sathyavrutha Kestra and said that Lord Narashima, who is the protector of Sathyavrutha Kestra gives 1000 times punya to each karma.
