Swami Mukundananda
Does the motive behind my seva matter?
Seva has three kinds by motive
Seva can be tamasik (in the mode of ignorance), rajasic (for prestige, name and fame), or sattvic, which is higher still.
Then there is rajasic seva: you offer money in a temple so that a fan is installed there with your name, your father's name and grandfather's name inscribed on it.
