This is the solitary lamentation of some devotee. Hari, hari is an exclamation of grief. “I spend my nights in intense contemplation, thinking in resignation, that since I am so disqualified, it will have to remain as such, unfortunately.” However, he describes himself as still being thirsty for seeing the lotus feet of the Lord. Therefore, he hangs his head in hopelessness. The genitive case is used for the speaker to show his lack of respect for himself.
