Swami Mukundananda
What are the different kinds of seva, and which kind is worth doing?
Seva in ignorance, passion and goodness
Seva can be tamasik (in ignorance), rajasic (for prestige, name and fame) or satvik, which is higher still. Paying a demand made under threat is an example of tamasik seva, and giving so your name is inscribed is rajasic seva.
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 your grandfather's name inscribed on it.
