Nice slokam

"तेसं जननी नित्ययुक्ता एकाभाक्तिर्विसिस्यते प्रियो ही ज्नानिनो 'तयर्थमाहम सा का मामा प्रियः " This Shloka tells that out of the devotees, there are some wise people who want something in return and the people who don't expect any fruit in return of the worship. God loves the people who don't expect anything in return as their love towards the god is true.
