A few years after her apparition to the Shepherd boy, Vailankanni was privileged to be blessed with another apparition of the Blessed Mother, and this time, to a poor lame boy of the village. At the close of the 16th century, there was a poor widow in the village of Vailankanni with a son who was congenitally lame. In order to eke out their existence the lame boy would sell buttermilk at a place known as 'Nadu Thittu'. It was a slightly elevated spot where there was a huge banyan tree with outstretched branches.he widow would carry the lame boy and leave at Nadu Thittu with a pot of buttermilk. The boy sold the butter milk to weary way-farers who would take shelter from the sweltering heat under the tree. On an extremely hot day the boy was waiting for his customers, but as no one turned up, he was a little disappointed.
But his disappointment turned into joy when, in the twinkling of an eye, he saw a Lady of stunning beauty standing before him, holding a baby of dazzling beauty in her arms. The Mother and Child were attired in impeccable white garments. The Lady looked at the boy with a charming smile and asked him for a cup of buttermilk for the child. Without a moment's hesitation the lad gave her a cup of buttermilk as he considered it a great honour and privilege to render a little hospitality to his seemingly ethereal visitors. With a sense of deep satisfaction the boy saw the Lady feeding her child with the buttermilk he had offered her. The Lady then cast a benevolent look at the lame boy and turned towards her Divine Child in her arms as if entreating him to heal the crippled lad. The Mother's silent request was instantaneously answered.
Without the boy realizing it, a miracle had been wrought on him, but he kept on gazing at his distinguished visitors as though entranced.
The Lady gratefully acknowledged the youth's generosity and requested another favour of him. The lad was to go to Nagapattinam and apprise a certain rich Catholic gentleman of the Lady's appearance to him and to inform him of her desire to have a chapel built at Vailankanni in her honour. While he was eager to carry out the mission entrusted to him, his physical impairment rendered him incapable of carrying out the mission. The boy told the Lady so. But the Lady bade him get up and walk as he was no longer a cripple. Immediately, the lad leaped to his feet. His joy knew no bounds when he realized he could walk. He ran as fast as his leg could carry him, all the 10 kilometers to Nagapattinam. On the way he would pause a while to make sure that the miracle that had taken place in him was not a figment of his mind but a reality.
On reaching Nagapattinam the boy, narrated to the gentleman of the apparition. He informed the gentleman that she had sent him as her emissary to ask him to build a chapel in her honour in Vailankanni. The gentleman had little doubt in believing the lad as he himself had a similar vision of Our Lady in his sleep the previous night, bidding him build a chapel in her honour. With the willing cooperation of the people of that locality whose enthusiasm had been kindled by the miraculous healing of the widow's crippled son, the Catholic gentleman of Nagapattinam soon put up a small thatched chapel at Vailankanni. An altar was erected in the chapel and a beautiful statue of Our Lady of Vailankanni holding the Infant Jesus in her arms, was placed on the altar. That marked the humble beginning of the Shrine of Our Lady of Vailankanni.
So many cures were taking place to those who prayed at the miraculous Mother with her Divine Infant came to be known as Our Lady of Good Health, Vailankanni (Vailankanni Arokia Matha). A chapel has been recently built at Nadu Thittu where Our Lady appeared to the lame butter milk vendor.
