The greatest achievement for a devotee is to become a servant of the servants. Actually no one should desire to become the direct servant of the Lord. That is not a very good idea. When Prahlada Maharaja was offered a benediction by Nrsimhadeva, Prahlada rejected all kinds of material benediction, but he prayed to become the servant of the servant of the Lord. When Dhruva Maharaja was offered a benediction by Kuvera, the treasurer of the demigods, Dhruva could have asked for unlimited material opulence, but he simply asked for the benediction of becoming the servant of the servants of the Lord. Kholaveca Sridhara was a very poor man, but when Sri Caitanya Mahaprabhu wanted to give him a benediction, he also prayed to the Lord to be allowed to remain a servant of the servants of the Lord. The conclusion is that being the servant of the servants of the Supreme Personality of Godhead is the highest benediction one can desire.
