Srimad Bhagavatam Canto 10, Chapter 81, Text 35

SB 10.81.35

kiñcit karoty urv api yat sva-dattam
 suhrt-krtam phalgv api bhuri-kari
mayopanitam prthukaika-mustim
 pratyagrahit priti-yuto mahatma
 
Translation: 
 
The Lord considers even His greatest benedictions to be insignificant, while He magnifies even a small service rendered to Him by His well-wishing devotee. Thus with pleasure the Supreme Soul accepted a single palmful of the flat rice I brought Him.
