Vyakhyana Saram:
Swami Desikan is saying that once lowly thoughts gain root in the mind of a person, they drive that person to performing cruel acts. This vicious cycle cuts the person down eventually. He seeks Lokacharyar's grace that flows like a flood from His divine eyes to not only remove this lowly act, but also to push him toward doing good deeds. He seeks that strength from Pillai Lokacharyar.
