Srimad Bhagavatam 3.13.13

3.13.13

येषां न तुष्टो भगवान् यज्ञलिङ्गो जनार्दन: । तेषां श्रमो ह्यपार्थाय यदात्मा नाद‍ृत: स्वयम् ॥ १३ ॥

yesam na tusto bhagavan yajna-lingo janardanah tesam sramo hy aparthaya yad atma nadrtah svayam

yesam
of those with whom
na
never
tustah
satisfied
bhagavan
the Personality of Godhead
yajna-lingah
the form of sacrifice
janardanah
Lord Krsna, or the visnu-tattva
tesam
of them
sramah
labor
hi
certainly
aparthaya
without profit
yat
because
atma
the Supreme Soul
na
not
adrtah
respected
svayam
his own self.

The Supreme Personality of Godhead, Janardana (Lord Krsna), is the form to accept all the results of sacrifice. If He is not satisfied, then one’s labor for advancement is futile. He is the ultimate Self, and therefore one who does not satisfy Him certainly neglects his own interests.
