Quoted Text

"Seva" is a Sanskrit word meaning selfless service.  Seva is doing good work, helping others, without attachment, and without any desire for personal gain.  Performing Seva on a regular basis is one way for us to become more aware of our connection with the divine.  Just one small act of Seva a day can bring about tremendous spiritual growth.
