From MS & Radha by Gowri Ramnarayan

One of her signature viruttams, which involved improvised ragas across an exquisite Tamil lyric goes :

Even if the mother forgets the child,

and the child forgets the mother who bore it, 

even if life forsakes the body, and the body forsakes the soul,

even if the heart abandons the art it had absorbed, and eyes fail to blink,

I shall not forget the lord who resides within pure souls
