Prayag Raj is the king of all pilgrimage centers because Lord Brahma conducted first (pra) ten yajnas (yag) there at Dashaswamedh Ghat also located in Daraganj.
Considering that Lord Brahma lives one hundred celestial years- equivalent to 311 trillion 40 billion earth years, and we are currently in fiftyfifth year of Brahma, and assumimg that Brahma performed first ten Yajnas when he was twenty years of age, it is established that it happened 110 trillions years ago."Lord Brahmā's day, consisting of his 12 hours, lasts 4 billion 320 million years, and his night is of the same duration.
Lord Rama visited Prayag twice. The first stay was at Bharadwaj Ashram which still exists near University of Allahabad. Lord Rama, Sita and Lakshmana visited the Veni Madhav Temple during their fourteen year long exile and it was at Daraganj where "Nishad", the king of boatsmen, helped them cross the Ganges river. After killing Ravana,the "Pushpak Viman" carrying Lord Rama, Lakshman and Hanuman and the victorious army of monkeys and bears stopped over at Prayag again where Lord Rama and Lakshman did "prayashchit" for having killed Brahmanas. This happened 1.7 million years ago in Treta Yuga. NASA photographs confirm the bridge made of boulders between Sri Lanka and India and predict it to be 1.7 million years old. The famous debate between Shankaracharya and Mandan Mishra and his learned wife Bharati Mishra took place in 700 AD- Bharati Mishra was the judge. When the couple lost the philosophical debate and was about to enter alive in the pyre- according to "rules of engagement" in those days- Shankaracharya granted them pardon and right to live, and preach Vedic knowledge rather than Buddhism.
About 500 years ago, Lord Chaitanya preached the essential principals of devotion to Rupa Goswami for ten days at Dashaswamedh Ghat. There is a plaque bear
