Gadhada Last Section Vach. 6 Vachanamrut Rahasyarth Pradeepika Tika

Consider a disciple of God who performs the nine-fold devotion, such as giving sermons (katha), singing devotional songs (kirtans) and listening to discourses (shravan). If he has jealousy (irsha) towards another disciple of God, then, God does not become immensely pleased by that devotion. If one discards all jealousy and performs devotion only for his own salvation, and not to show others, God becomes pleased with that devotion. Therefore, anyone who wants to please God should not perform devotion in order to show others or because of jealousy towards someone else; he should do so only for his own salvation.
