Premanand Maharaj Ji
Why does my seva feel incomplete even when I serve outwardly well?
Seva needs constant remembrance
Seva brings likes and dislikes, attachment and aversion, honour and insult. Keep remembrance of Bhagwan's Name going; without it seva is considered incomplete.
If remembrance is going on all the time, the seva will be done very well. If remembrance is not going on, the seva is considered incomplete.
