As one who never saw the inside of a school, and grew up as the hidden "lamp in a pot" which shone at home, Mathaji Vithamma today shines as the bright light on the Hill, speaks fluently in Tamil and English to all those who seek her, allays their woes, and treats them with Sidhdha medicine by the grace of the Guru. With the blessing of Sri Muthukrishna Swamiji and under the guidance of Mathaji Vithamma , her disciples are carrying out several charitable services at the holy Kshetram of Sri Pothai.
