Once Maha Vishnu mitigated the sufferings of Suryan who is also called Aadityan. Since Kesavan blessed Aadhityan, he is called Aadhi Kesavan. Aadhi means "first" in the world. When Gajendra the elephant was caught by the crocodile, he shouted "Aadhi Moolame" and prayed to almightly to protect him. Thus Aadhi Moolam refers to Aadhi Kesavan.
Chandran is cursed: A curse befell Chandran[Moon]. After roaming aimlessly, he came to Mylapore. Maha Vishnu in order to bless Chandran asked at the holy rivers of India to confluence at Kairavani Pushkarini and help Chandran to get rid of his curse.
The rivers obeyed Maha Vishnu and flowed to Kairavani Pushkarini. Chandran has a holy dip at the holy waters and propitiated the Lord. All the rivers requested the Lord to bless them and returned to their respective places. Aadhi Kesavan requested all the rivers to stay back with him at Mayurapuram. All the holy rivers blessed Chandran. Thus the holy water is called "Sarva Theertham". Since Chandran got rid of his curse, it is called Chandra Pushkarini. Over the years it came to be called "Chitra Pushkarini" but now it is called as "ChitraKulam".
