If we really want to give Krishna pleasure, then we should think about what He likes the most. Whenever there is an object of service and a person, we should wonder what would most please that person. Service to Krishna, service to Lord Caitanya, and service to the devotees are synonymous, because the object of the service is to satisfy the beloved. By satisfying those persons, we too become satisfied.
