Vyakhyana Saram:
Vedas are a dense forest and it is easy for someone to get lost in them and lose direction. Only the great acharyas can walk through that forest and shed light on the correct path to the common people. Desikan is saluting Pillai Lokacharyar for doing that and showing the path of prapatti such that even the ordinary person can walk through it.

In his work Sri Vachana Bhushanam, Pillai Lokacharyar says that any one can perform prapatti at any place, at any time and for any reason. The only condition is to whom it is performed. Through such churnais, Pillai Lokacharyar has cleared this path and made it available to everyone.
