Sometimes we think unity is when we are doing everything together. This is beneficial when we are collectively endeavoring to engage in the sankirtana movement—to distribute the glories of the Lord, to maintain Srila Prabhupada’s temples, to worship the deities, etc. However, doing service together does not only mean being physically together; it also means sharing a common consciousness or goal in those endeavors. That common consciousness is the desire to please the Lord without anything in return for that service. Devotees who work together in Krishna consciousness in this way will see that here is no disunity.
