as this fruit was divinely sweet and was infinitely delicious compared to the previous one, her husband inquired as to how ammaiyar obtained this mango. subsequently,karaikkal ammaiyar worshiped lord's feet and revealed the truth to her husband, who didn't believe it. he asked her to show another mango with divine help. ammaiyar prayed to lord shiva for another mango. immediately lord shiva gave her a similar mango,which she gave it to her husband. the mango then disappeared, and paramathathan realised the divine nature of his wife. he understood that ammaiyar was worthy of worship and she cannot be treated as his wife. he then deserted ammaiyar, becoming a trader and married the daughter of a merchant who then gave birth to their child. paramathathan named the child with the real name of ammaiyar, punithavathi. when the word reached ammaiyar's family, they decided that they must take her to him. when he saw his former wife, paramathathan addressed her reverentially, saying that he realised ammaiyar was no ordinary human being. he worshipped her with his wife and child. ammaiyar prayed to lord shiva asking for a boon that she may worship lord shiva as a disembodied wraith. she received the boon, and leaving all her beauty and her body behind.this was the reason of formation of this grand festival of mangani.
