A small story:
An NCC teacher told all his NCC students, 'Everyday, you should do one good activity and come and report.'
One day, three boys stood up and said, 'Sir, today we helped an old lady to cross the road.' The teacher was surprised and curiously asked, 'Why do you need three persons to help one lady across the road?'
One of the boys replied, 'Yes Sir, it took three persons because she didn't want to cross!'
Understand, many times, your service ends up in imposing your ego. So, let you bring a smile on your face, let a deep contentment settle. I always tell people, if you can solve all the problems of your life, just by your knowledge-weapons, shaastra-shastraas, inner clarity, inner healing, then start doing service.
First thing you need to do is solve your life by having the clarity about jeeva, jagat and ishwara. Jeeva is Self, jagat is world, and ishwara is god, source of the world and self. Then start doing service. Work intensely for this inner clarity within yourself.
