Om Swami
Why does seva ask for sacrifice, and who am I really serving?
Service involves sacrifice
Service involves some sacrifice: even if you don't want to do the task, you do it because the person asking for service needs it. The same God resides in everyone, so enhance your own life and the life of others.
Service involves some sacrifice, in the sense that even if I don't want to do this, I will do it because the person asking for service needs it.
