SB 10.81.3
sri-bhagavan uvaca
kim upayanam anitam
brahman me bhavata grhat
anv apy upahrtam bhaktaih
premna bhury eva me bhavet
bhury apy abhaktopahrtam
na me tosaya kalpate
Translation:
The Supreme Lord said: O brahmana, what gift have you brought Me from home? I regard as great even the smallest gift offered by My devotees in pure love, but even great offerings presented by nondevotees do not please Me.
