10.84.62

अस्मास्वप्रतिकल्पेयं यत् कृताज्ञेषु सत्तमै: । मैत्र्यर्पिताफला चापि न निवर्तेत कर्हिचित् ॥ ६२ ॥

asmāsv apratikalpeyaṁ yat kṛtājñeṣu sattamaiḥ maitry arpitāphalā cāpi na nivarteta karhicit

asmāsu
to us
apratikalpā
incomparable
iyam
this
yat
since
kṛta-ajñeṣu
who are oblivious of the mercy that has been shown them
sat-tamaiḥ
by those who are most saintly
maitrī
friendship
arpitā
offered
aphalā
unreciprocated
ca api
even though
na nivarteta
it does not cease
karhicit
ever

Indeed, the Supreme Lord must have created the bonds of affection, for such exalted saints as you have never stopped showing matchless friendship toward us ingrates, although it has never been properly reciprocated.
