Vyakhyana Saram:
Those who desire to attain moksha through bhakti yoga have to do karma yoga first. As part of the karma yoga, they have to perform yagas and other acts. Swami Desikan says that his mind shudders upon hearing that. This is due to the fact that we have no strength to follow these strict rituals. Upon hearing the Srisuktis of Pillai Lokacharyar (such as Sri Vachana Bhushanam) that clearly delineate that Sriman Narayana gives moksha to us without desiring anything in return (nirhetuka krupa), Vedanta Desikan says that his fear was removed and his mind became happy.
