Do actions without expectations

One of the devotees asked Nannagaru - "You are saying that silence is gold, how can we reach the silence and receive that gold?"

Sri Nannagaru was in silence for a few minutes.

Then he addressed the question - "You don't have the right to Eternal Knowledge(jnana). To reach the state where you can understand jnana, you have to do work/actions(karma) without ego. Your actions should be without expectation from others and filled with devotion. The Guru's grace is needed to understand this Eternal knowledge (jnana)".
