Who is a real guru? Guru means that he says Krsna is Bhagavan, not that he claims to be Bhagavan. Real guru teaches how to serve Krsna. To meet guru is a very rare thing. By service our eyes are opened to see guru. The process is not complete until we go deeper and really understand who he is in reality. Guru is a servant not an enjoyer or exploiter.
Prema is the goal and when we have prema we will have unlimited energy to serve. God gives us something that money can't buy. He fulfills all desires and saves us from calamities.
