During the sixteenth century, a young Hindu boy was carrying milk to a customer when he stopped to rest beneath a Banyan tree beside a small pond. There, Our Lady appeared to him with the Infant Jesus and asked for some milk. The boy offered it, and when he finally reached the customer, he explained why he was late and why the pot seemed lighter. But when the man checked the pot, it was miraculously full. Realizing something extraordinary had taken place, he accompanied the boy back to the pond. At that very spot, Our Lady appeared again. The local Catholic community rejoiced when they heard of the apparition, and the pond became known as Matha Kulam—Our Lady’s Tank.
Some years later, Our Lady appeared once more, this time to a disabled boy selling buttermilk on the outskirts of Vailankanni. She asked him for buttermilk for her Son, and after he gave it, she instructed him to deliver a message to a wealthy Catholic man in Nagapattinam. Only when he stood up to leave did the boy realize he had been healed. Meanwhile, the man in Nagapattinam had already received a vision the night before, in which Our Lady asked him to build a chapel. The man and the boy went together to the place of the apparition, where Our Lady appeared to them both. In response, the man built a simple thatched chapel on the site, which soon became a place of devotion to Arokia Matha, Mother of Good Health.
A few years later, Portuguese sailors caught in a fierce storm prayed to Our Lady for help. They survived the wreck and were brought ashore at Vailankanni by local fishermen, who led them to the small chapel. In gratitude for their rescue, the sailors built a more permanent chapel and later expanded it on subsequent visits. They dedicated it to Our Lady on September 8th, the feast of her nativity, marking the day they were saved.
Basilica of Our Lady of Good Health Vailankanni is based in Velankanni, Tamil Nadu, India.
