In plain words
Amutaṉār: In former days [before creation], when my mind and all my faculties had fallen apart and I lay sunk at my end, Araṅgaṉ saw it and in his grace gave them to me then; yet even he did not give me his feet. My father Rāmānuja came, gave me those feet himself, and today lifted me up [out of saṃsāra].
