When you begin service, it’s actually a natural urge. But at the start, you still have to learn a lot of things..
1) Your urge for perfection makes you bossy and irritates others and they move away
2) Then you may fall into urge for seeking love, attachments, attention, group and deviate
3) In the early days, you have ‘doership’ attitude that ‘I am doing it’, ‘because of me’, which dissolves with experiences
At the end, when you come out of all of it, being human, you keep experiencing traces of it in day-to-day life, but the urge for seva never dissolves. It may reduce for sometime in between, you may not do seva for some time, but the urge is a natural urge.. and when the break is over, you are going to be back to serving.
