Service is a privilege which is extended to a conditioned soul by the mercy of guru.
Seva is your only passage to the spiritual world.
If you always try to serve others, you can never make offenses.
Enthusiasm and eagerness in service is the difference between a hollow ritual and a genuine act of devotion.
Service should arise as a by-product of inspiration as it is a devotional exchange between the Lord, Supersoul and jiva.
Every service has a heart, and that heart is Krishna Himself. So when you put your heart into that service, then you will enter the heart of Krishna.
