न च तस्मान्मनुष्येषु कश्िचन्मे प्रियकृत्तमः। भविता न च मे तस्मादन्यः प्रियतरो भुवि ॥

na cha tasmān manuṣhyeṣhu kaśhchin me priya-kṛittamaḥ bhavitā na cha me tasmād anyaḥ priyataro bhuvi

Nor is there any among men who performeth dearer service to Me than he, nor any other shall be more beloved by Me on earth than he.

In plain words: Krishna says no one does him a dearer service than the person who shares this teaching, and no one on earth will be more loved by him.
