Question: I would like to know why the enthusiasm gets lost and besides having a lot of service, there is no enthusiasm for doing it, and why, although Gurudeva is there, willing to hear, one cannot speak with him and tell him what one feels about the service, but prefers to keep quiet?
Answer: This question comes from the typical case of a devotee who listens too much to the mind. First we should be thankful. Next we should be compassionate. If you have no enthusiasm to help others, it means that you forget the sweet will of Lord Krishna. He said, that dearest of all to Him is the one, who takes His message to others.
Just look at the example of our acaryas, they all went on with their service, despite a lot of hardship and difficulty. We should rather follow them than listening to our mind. The mind is great if it comes to cheating yourself and producing excuses for not serving and not surrendering. So the problem is common, and it will continue until you give a good kick to your mind with a lot of maha-mantra, reading the transcendental books, hearing lectures or asking for personal guidance from an advanced devotee.
I think you would agree, that there are many people in this world who are much worse off then you. Do you agree? If you say: 'yes', then get out there and do something to help them, rather than to lament like an old women, because her partners for playing bridge did not show up. This life is very serious and it will never get more serious then practising devotional service, because even at the moment of death, only the Holy Name will save you.
Please do not take offence of my strong reply, but sometimes only a strong reply awakens us from our sleeping conditions.
